Configuring SNMP OID for Memory Utilization Monitoring

  1. In this article we look at how to configure the SNMP OID for memory utilization monitoring of specific device. If you do not know the OID for a device, contact the device manufacturer and request the OID for the function required.

Procedure

Step 1. Right-click on the device that required RAM utilization monitoring and select View Device Info.

Step 2. The View Device Info window opens. Click on SNMP OID.

Step 3. The SNMP OID window opens. Examine the entries for “platform specific oid memory utilization.” In this case two OID entries have been made. Depending on the manufacturer, one or two entries will be entered.

Step 4. If there are no entries, then SNMP OID need to be entered to enable the memory utilization monitoring.

Step 5. To enter platform specific OID for memory utilization, click on the text.

Step 6. The SNMP OID (memory utilization) window appears.

The manufacturer will tell you how the device reports memory utilization. If the device reports Memory Utilization Percent directly, the OID is entered in that box and provisioning is done. If the device reports separate values for total, free or used, then the OID information for each count need to be entered. Nectus will perform the calculation to arrive at Memory Utilization.

For example, when the device reports Memory Utilization Percent directly, the OID is entered in the first box and provisioning is complete.

In this case, the device reports Memory Used and Memory Free, so the OID for Memory Used is entered in the Memory Used space and the OID for Memory Free is entered in the Memory Free space. Nectus will compute utilization as Memory Used / (Memory Used + Memory Free) * 100.

In this case, the device reports Memory Free and Memory Total, so the OID for Memory Free is entered in the Memory Free space, and the OID for Memory Total is entered in the Memory Total space. Nectus will compute utilization as Memory Free / Memory Total * 100.

Step 7. Click on the OK button. Nectus will provision the OID information, unless an error is discovered.

In this case Nectus is reporting that Used and Free Memory OIDs are required.

We re-enter the OID information as Memory Used and Memory Free, and click OK.

Step 8. The OID assignments are accepted and displayed on the View Device window.

Testing

  1. Testing: Testing the assignments can be done by examining the utilization display or retrieving the OID contents.

Step 1. Click View Device General to see the results of configuration.

RAM percent utilization is working.

Step 2. Testing: Click on the dial to see a graph of the measurement over time.

Step 3. Testing: To retrieve current value of OID select SNMP OID tab and click on “TEST” for OID of interest.

Step 4. Change SNMP Walk to GET.

Step 5. Click Start.

Step 6. Current value of the OID will be displayed.

How to install SSL Certificate for Nectus GUI

,

This guide explains how to generate the CSR code and install a commercial SSL certificate for Windows Apache so that you could access your Nectus GUI page securely via HTTPS.

It assumes that during Nectus installation, you selected the default location which is C:\Program Files\Nectus.

If you installed Nectus in a different folder, make sure to adjust the commands and locations given in this guide accordingly.

In general, in order to have a website accessible using secure HTTPS connection, the web server must have a pair of public and private keys configured.

The public key must be signed by a trusted Certificate Authority and added to a digital SSL certificate.

To obtain that certificate, you will need to send the certificate signing request (CSR) code to your SSL provider. Please refer to instructions below:

Generating CSR using OpenSSL

  1. On your Windows server, press Win+R, enter cmd and hit OK

 

2. Enter the following command to run OpenSSL: “C:\Program Files\Nectus\Web\Apache24\bin\openssl.exe”

 

 

3. The prompt will change to OpenSSL>. This means we can run the OpenSSL commands now.

To generate a new CSR/Key pair for your future SSL certificate, execute the following this command:

 

req -new -newkey rsa:2048 -nodes -keyout “C:\Program Files\Nectus\Web\Apache24\conf\yourdomain.key” -out “C:\Program Files\Nectus\Web\Apache24\conf\yourdomain.csr” -config “C:\Program Files\Nectus\Web\Apache24\conf\openssl.cnf”

 

4. You will be prompted to enter certain information related to your domain.

The commentaries for each field are provided after the // sign.

Country Name (2 letter code) [AU]:US // enter the ISO 3166-2 compliant country code here

State or Province Name (full name) [Some-State]:California // the field for the state

Locality Name (eg, city) []:Los Angeles // the field for the city

Organization Name (eg, company) [Internet Widgits Pty Ltd]:NA // the name of your company. If you do not have a company or do not wish to indicate it, simply put NA

Organizational Unit Name (eg, section) []:NA // a department of your company. NA can be used here

Common Name (e.g. server FQDN or YOUR name) []:example.com // this is the field for your domain

Email Address []:. // this field is not required generally so you can leave it blank

Please enter the following ‘extra’ attributes

to be sent with your certificate request

A challenge password []:. // can be left blank

An optional company name []:. // can be left blank

 

5. Once done, the C:\Program Files\Nectus\Web\Apache24\conf\ directory will have two new files, the file with the CSR code (.csr) and the file with the private key (.key).

We’ll leave the private key for the time being. The CSR code has to be provided to your certificate vendor — this code is the base for your commercial SSL certificate.

Please contact your SSL vendor for instructions with SSL activation.

6. When the SSL is issued, you should receive at least two files: SSL certificate in a .crt (or .pem, .cer) file, and the CA-bundle (also can be called intermediate CA, root CA certificates) with extensions like .ca-bundle, .crt.

Please note that Apache requires only PEM-encoded certificates, so PKCS#7 or PKCS#12 encoded SSLs won’t work.

Configuring SSL for Apache

7. Upload those files to the C:\Program Files\Nectus\Web\Apache24\conf\ directory.

8. Then, go to the C:\Program Files\Nectus\Web\Apache24\conf\extra folder, and open the httpd-ssl.conf file in Notepad.

9. Find and edit the following directives and make sure that they point to the SSL certificate, Private Key, and the CA-bundle files accordingly:

 

SSLCertificateFile “${SRVROOT}/conf/yourdomain.crt”

SSLCertificateKeyFile “${SRVROOT}/conf/yourdomain.key”

SSLCACertificateFile “${SRVROOT}/conf/yourdomain.ca-bundle”

 

Note that the SSLCACertificateFile directive is commented out by default. You need to delete the # sign at the beginning of the string to uncomment the directive.

10. Save the configuration file

11. Return back to the C:\Program Files\Nectus\Web\Apache24\bin folder and double-click on ApacheMonitor.exe

 

12. The ApacheMonitor app will appear in the system tray at the lower right corner of your screen. Find and click it there.

13. Hit “Restart”

 

14. Now you can try accessing your Nectus GUI page in the browser via HTTPS: https://yourdomain.com

Configuring Linux Monitoring in Nectus

,

Configuring Linux Monitoring in Nectus

Nectus Server 1.55 adds feature to monitor some system parameters on hosts running Linux. Enabling this feature for your infrastructure requires two steps:

  • Configuring of Nectus Server;
  • Installing and configuring of Nectus remote agents on target Linux machines.

This guide describes steps for Nectus Server configs. Installing and configuring of Linux remote agents are described here.

Linux monitoring integration

Choose the following menu item from the Nectus GUI to set global Linux monitoring parameters.

This will open the next window:

  • Agent mode determines whether the agent runs in passive mode (when it waits for an incoming connection from the server and then collects the required metrics) or in active mode when the agent connects to the server pro-actively and sends the collected data.
  • Server TCP port sets the server port number for incoming connections from the agents running in active mode. If you set Agent mode to passive then this value is not used.
  • Pre-shared Key determines the secret key used to encrypt and decrypt messages between Nectus Server and the monitoring agents. You can set string of any length but recommended length is from 8 to 16 characters. The exactly same key should be set in all agents’ configuration files (parameter SERVER_PRESHARED_KEY, see details here).

Click OK to save configured parameters.

 

 

Select “Linux Monitoring Settings” from the “Monitoring” menu to configure your monitoring profiles for Linux machines.

Click “Create” to create a new monitoring profile:

In the following form enter the name of your profile and choose metrics you would like to monitor:

 

Configure the necessary metric parameters like minimal and maximal thresholds, alerting etc.

You can create any number of profiles and assign each of them to different group of Linux machines.

Linux Servers

 

Select “Linux Servers” from the “Inventory” menu to configure groups and servers to be monitored.

Click “Create new Group” in the next form:

 

Enter “Group Name” for the new group, select “Enable monitoring” and choose the desired Monitoring Profile for this server group:

Also select the appropriate alert recipients in this form.

You can create any number of monitoring groups if you need to apply different profiles or alert recipients for different server groups.

When you have finished with the groups switch to the next tab “Servers” in the same form and click “Add Server” to add a Linux server to be monitored:

In the next window enter the Hostname (optional, it will be obtained later during the monitoring process), IP address, TCP port of the remote agent’s listening socket (default 5400) and choose the appropriate Group:

You can choose different values of TCP port for different servers according to your network configuration. But note that this value must match the parameter AGENT_PORT set in the agent’s configuration file (see details here).

After clicking “OK” you will see the server in the following list and you will be able to View, Edit and Delete the server (operations are marked with a red square).

After you have added all the desired servers and installed the remote agents the process of monitoring of your Linux hosts will start automatically.

 

Device View Auto Population Rules

, ,

Device View Auto Population Rules

Device View is the logical grouping of the devices that can be used in different places within the Nectus application. In the previous versions of Nectus, the user would manually add devices into device views which may become a significant management overhead.

In Nectus version 1.55 we introduced an ability to automatically populate device views based on specific conditions such as device names, types, etc.

User can define a set of conditions which has to be true for Nectus to automatically add devices to device views.

This article will guide you through the process of defining the auto population rules for device views.

To access your SNMP Device Views go to Inventory Views SNMP Device View

 

 

To add a new Device View, click Create in the upper right hand corner of the SNMP Devices Views page.

 

Give a name to your new Device View.

 

.

Press Save button to finish creation of Device view.

 

Open again newly created device view and in the upper right-hand corner, select Edit Rules.

This will open the Devices View Auto Population Rules page.

 

Select the plus sign to add a new Auto Population Rule.

 

Add all the required Auto-population rules and press Ok button to Save.

If multiple rules are defined all the rules must be TRUE for device to be automatically added. (Logical AND).

Your rules will be processed daily at 3:00 PM.

If you would like to apply your rules immediately, press the Apply Rules button.

 

Monitoring BGP Sessions with Nectus

,

Monitoring BGP Sessions with Nectus

Nectus 1.2.53 introduces ability to automatically discover and monitor iBGP and eBGP sessions across all router types and manufacturers.

Nectus scheduled network discovery automatically finds all the BGP sessions via SNMP polls and adds it to Nectus database where user can group them by type and enable active monitoring and alerting.

BGP Session Discovery

As part of regular scheduled network discovery Nectus detects all existing BGP Sessions and adds it to one of the existing BGP group which has “Default” flag set to ON.

You can see all the BGP sessions that were discovered in Inventory -> BGP Sessions or in left side panel called “BGP Sessions

 

If you right-click on BGP Session and select “Properties

 

.. you can assign a human friendly name or change a group membership for any of the BGP sessions.

 

You can create multiple BGP session groups and assign discovered BGP sessions to different groups according to its type or functional purpose.

To create a new Group, right-click on “BGP Sessions” line and select “Add New Group” on context menu.

 

Configure New Group name, set “Enable monitoring” to ON if you want all BGP Sessions in this group to be monitored for UP/DOWN Status.

 

If you set “Default” value to ON, this group will become a group where all newly discovered BGP sessions be added automatically. Only one group can have “Default” value set to ON

You can also assign BGP Session to a Group by right-clicking on BGP session and selecting “Move BGP Session to..” option

 

 

By clicking “View Session Info” on BGP Session context menu you can view detailed information about BGP Session

 

 

After you finished creating BGP session groups, assigning BGP sessions to corresponding groups and enabling BGP session groups for Monitoring the final step is to enable BGP Sessions monitoring in corresponding SNMP Device Monitoring Profiles that are applied to the routers that terminate all the BGP sessions.

Find required SNMP Monitoring Profile and enable “BGP Session Status” Monitoring Option

Now are you all set to start monitoring your BGP sessions line a pro.

 

UPS Health Status Monitoring with Nectus

,

UPS Status Monitoring with Nectus

Health monitoring of UPS units is one of the most critical tasks of network infrastructure monitoring.

If UPS fails during power outage it results in immediate network downtime resulting in loss of revenue and degrading user experience.

Most of the modern UPS Units perform daily self-tests and results of those self-tests are available via SNMP protocol.

Our goal is to collect those self-test results on regular basis and generate an alert or incident when self-test indicates a UPS failure.

Step 1. Determine which SNMP OID to use

Very first step before you can start monitoring UPS health status is to determine which SNMP OID contains self-test information for your UPS units.

You can open a support case with your UPS vendor and request SNNP OID string for self-test information.

For example, SNMP OID for self-test information from UPS manufactured by APC is .1.3.6.1.4.1.318.1.1.1.7.2.3.0

This OID returns following values:

1 = Ok

2 = Failed

3 = Invalid Test

4 = Test In Progress

 

Step 2. Create Device View that contain all UPS units

Next step is to create a Device View that contain all UPS units that we want to monitor.

To create a Device View go to Inventory -> Views -> SNMP Device Views.

 

Create a new Device Vice called “UPS Units”

 

 

Step 3. Create Custom SNMP Tracker for UPS Self-Test Info

Now we are ready to create a custom SNMP tracker that will be polling our UPS units every 5 min for self-test information.

In Nectus GUI go to Monitoring → SNMP Monitoring Settings → Custom SNMP Trackers

Suppression of Frequent Identical Alerts In Nectus

Suppression of Frequent Identical Alerts In Nectus

Often when a network device or interface changes its state between Up and Down multiple times in a short time interval, numerous identical alerts will be sent to all the configured alert recipients.

Nectus offers the ability to suppress frequent identical alerts to reduce informational noise level by specifying a suppression timer for up to three hours.

Nectus calculates a CRC hash value from each of the email alert bodies and if hash values of two alerts are matching they are considered to be identical and can be suppressed.

Nectus excludes event timer values and specific metric values from hash calculation logic. You can configure the suppression timer from 0 to 180 minutes where 0 means no suppression.

To configure the suppression timer, go to    Monitoring -> Global Monitoring Settings

 

 

Under Monitoring Settings, select the Alerts tab.

To enable suppression specify a time interval from 1 to 180 minutes.

At the end of the time interval, alert logic will resume as normal.

Setting timer to 0 will disable the suppression.

Configuring WMI Integration in Nectus

Nectus uses WMI Interface in several of its modules.

List of modules that depends on WMI Integration:

  1. Windows Server Monitoring Module
  2. IPAM Module

In Windows Server Monitoring module Nectus uses WMI interface to poll Windows Servers for critical health metrics such as CPU and RAM Utilization etc.

In IPAM Module Nectus uses WMI interface to interact with Microsoft DNS and DHCP servers while Importing and creating reservations.

WMI Integration settings must be complete before Nectus can communicate with Windows Servers in those modules.

To complete WMI Integration go to Settings -> General Settings -> WMI Integration

Click on “WMI Integration” link and complete all the required fields for WMI Service account

that will be used by Nectus connect to Windows Servers via WMI Interface.

WMI Service account should not have password expiration policy to prevent Integration from breaking every time password has to be changed.

Use “Test” button to test Service account credential against any of Windows Servers of your choice.

After connection “Test” is passed WMI Integration is complete.

 

Adjusting min. detectable ICMP outage duration in Nectus

,

Adjusting Min. detectable ICMP outage duration in Nectus

When Nectus is configured to monitor UP/DOWN Status for network devices with ICMP it sends Echo packets at preset interval called Inter-Packet Delay.

By default, this Interval is set to 10 seconds.

Network Device is considered down if Echo-Reply is not received for “N” consecutive Echo packets.

By default “N” is set to 10.

So, by combining Inter-Packet Delay and “N” Value we can see that minimum duration of the outage that can be detected by Nectus with default settings is 100 seconds.

Sometimes when network a prone to fast transient outages or burstable traffic patterns that can impact ICMP it may be beneficial to increase minimum detectable ICMP outage duration to higher value. This can helps to eliminate alerts about short lived outages and only alert on outages that have more lasting impact.

To adjust Inter-Packet Delay or “N” Value go to “Monitoring -> Global Monitoring Settings

 

And adjust values on “ICMP Monitoring” Tab according to your business needs.
