Configuring SNMP OID for Memory utilization Monitoring

Network Monitoring, Technical Notes

Configuring SNMP OID for Memory Utilization Monitoring

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

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 Manually Generate a Process Dump using Process Explorer

Network Monitoring

Problem

There may be times where a process dump file (or files) are required to troubleshoot a specific problem. The steps in this document walk through the process of generating a dump file using Process Explorer for IBM Support analysis. While the example used covers the tm1sd.exe process, the same steps can be followed for any process on the operating system. NOTE: You may follow a very similar approach using only Windows Task Manager, however Windows Task Manager will not allow you to choose a dump file location. This step is important if your application consumes a lot of memory and you do not have enough disk space on your Windows drive (C:).

Resolving The Problem

Download Process Explorer
- See: https://technet.microsoft.com/en-us/sysinternals/processexplorer.aspx
Locate your Process Explorer executable, procexp64.exe.
Right-click the process and select run as an Administrator.
When Process Explorer has opened, look for the process/executable name in the Process column.
- If more than one process with the same process/executable name exists, hover over the executable and review the Services parameter and confirm that the details match what you are expecting.
Once the correct process has been found, right-click the process and select Create Dump > Create Full Dump
When prompted, specify the directory where you wish to write the dump file to.
- Ensure that the disk you are writing to has enough space to write the file.
- The file will be close to the size of the memory used by the process.
After you click the Save button, it can take a few minutes for the file to finish writing to disk.
- During this time the process will freeze until the dump has been written.
The resulting dump file should be compressed and provided to IBM Support for review.

Monitoring BGP Sessions with Nectus

Network Monitoring, Technical Notes

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

Network Monitoring, Technical Notes

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

Press “Create” button to bring up Custom SNMP Tracker creation interface.

Complete tracker General information tab with correct SNMP OID and select Device View that contains all UPS units that we want to monitor.

Select Email and SMS list for Alert Recipients.

In “Alerts” Tab we need to specify which status values will be considered Normal and which values should trigger Alerts.

You can specify multiple values separated by comma.

Define an Alert Severity level for Alarm Values as Informational, Warning or Critical.

Define number of consecutive readings for which UPS self-test status must report an Alarm condition before formal Alert is created.

Nectus performs one SNMP poll per 5 min.

If you define value for consecutive readings as 3 it should result in Alert created after 15 minutes of True Alarm conditions.

Press “Save” to complete Custom SNMP tracker creation for UPS Status Monitoring

This completes creation of custom tracker that will be monitoring UPS self-test information on all APC UPS units in your network.

Suppression of Frequent Identical Alerts In Nectus

Network Monitoring, Technical Notes

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.

Adjusting min. detectable ICMP outage duration in Nectus

Network Monitoring, Technical Notes

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.

Multiple Alert Email Aggregation in Nectus

Network Monitoring, Technical Notes

Multiple Alert Email Aggregation in Nectus

Very often during site level power or network outages or during network maintenance multiple devices become offline at the same time causing multiple individual DOWN Email alerts to be sent at the same time.

Depending in the size of the site it can be well over hundreds or even thousands alert emails to be sent out to corresponding e-mail recipients configured for given site.

Starting from version 1.2.52 Nectus offers an option to aggregate multiple DOWN or UP email alerts into a single multi-device alert notification containing a list of all devices that became DOWN or UP within last monitoring interval.

To enable Alert Aggregation, go to Monitoring -> Global Monitoring Settings: “Alert” Tab

And Select “Aggregate multiple UP/DOWN Alerts” Option.
