How to Override Group Based Monitoring Settings for Specific Devices

By default, all the monitoring settings for each device are defined in the Monitoring Profile that is assigned to

Monitoring Group where this specific device is a member of.

Starting from 1.67.1 release Nectus adds ability to override group-based monitoring settings for each device.

Step1: Login to the Nectus Portal and go to the specific device on which you need to perform the monitoring settings override.

Right click on the device and select Properties.

Step 2: Select Metrics Tab in the properties modal and apply all the required overrides to the required metrics.

Check button “Local Override” must be selected for all the metrics that must have priority (override) over Group based monitoring settings.

Network device monitoring in Nectus  is controlled by device monitoring groups and associated monitoring profiles.

There are two default monitoring groups: “Default Monitoring Group” and “No Monitoring Group”

By default all devices are automatically assigned to Default Monitoring Group where all basic monitoring metric are enabled.

“No Monitoring Group” is used as a parking place for devices that do not required monitoring.

In some cases additional  monitoring groups may be required and this article explains the steps required to create  additional monitoring groups.

Step 1: Login to the Nectus Portal and go to Monitoring -> Network Monitoring Settings -> SNMP Devices Monitoring Settings.

Step 2: Monitoring Profile Creation – Go to the SNMP Device Monitoring Profile by clicking the Add Profile button. Name the profile, enable the relevant options, and click the OK button.

Now, we can see that the newly created profile is shown in the table.

Step 3: Monitoring Group Creation – Next, let’s go to the SNMP Device Monitoring Groups tab and create a new device monitoring group.

Step 4: Assigning Devices to Monitoring Group – Click on the device group name to add the appropriate device information to the group and lastly click on Save and Ok buttons.

Step 5: Assigning Monitoring Profile to Monitoring Group – Enable the monitoring and select the previously created monitoring profile from the dropdown.

Step 6: Defining Alert Recipients for Monitoring Group – Now, let’s configure recipients for alerting by clicking the email button. It allows us to add SMS and email recipients to a list.

Done.

Automating Selection of Interfaces Enabled for Monitoring

By default, Nectus does not monitor any Interfaces and you must select which interfaces you want to be monitored.

You can select Interfaces manually by adding it to one of the Interface monitoring groups or you can build auto-population rules

that will automatically select Interfaces based on predefined rules. Rules will be executed once a day (at 2:00AM)

Step 1: Login to the Nectus portal and go to Monitoring -> Network Monitoring Settings -> SNMP Interfaces Monitoring Settings option.

Step 2: Go to the SNMP Interfaces Monitoring Groups tab and click on the Auto Population Rules under the Default Monitoring Group.

Step 3: Click on the Rule to add a new auto-population rule. Once a day, interfaces that conform to the defined rules

will be added to the corresponding monitoring group.

You can add individual rules or you can create group of rules with AND/OR logic.

How to Monitor Number of Active TCP Sessions on PaloAlto Firewalls

Quick Start

Step 1: Login to Nectus and go to Monitoring -> Network Monitoring Settings -> Custom SNMP Trackers.

Step 2: Click on the Create button to create a new SNMP Custom Tracker that will be collecting number of active TCP sessions every 5min.

Palo Alto SNMP OID that returns number of active TCP sessions: 1.3.6.1.4.1.25461.2.1.2.3.4.0

Step 3: Enable the tracker, provide the tracker name, SNMP OID, unit name and data type.

Alerting option can be enable with predefined threshold value.

Step 4: If not created in advance, create the SNMP Device View by clicking the + (plus) button.

Provide the view name and select the Palo Alto Firewalls from available device list for monitoring.

Click “Ok” to finish tracker creation.

Step 5: For reporting, Go to the Reports -> “Top” reports -> Top Custom SNMP Trackers

Step 6: Select the appropriate report and tracker name to get the max. and min. values.

Click on the Graph button to get the tracker trend in visual form.

Done.
