Citrix Netscaler
Plugin: go.d.plugin Module: snmp
Overview
Monitor Citrix Netscaler (loadbalancer) with Netdata over SNMP. Netdata recognizes the device automatically by its sysObjectID (recognized across 1 device identifiers) and collects the metrics this profile declares — on top of the generic SNMP baseline — with no manual OID configuration.
Netdata's SNMP collector matches the device to the citrix-netscaler.yaml profile via sysObjectID/sysDescr, then polls the OIDs it declares.
This integration is supported on all platforms.
This integration supports multiple instances configured side-by-side.
Default Behavior
Auto-Detection
Auto-detected as Citrix Netscaler via sysObjectID/sysDescr.
Limits
The default configuration for this integration does not impose any limits.
Performance Impact
The default configuration for this integration is not expected to impose a significant performance impact on the system.
Setup
You can configure the snmp collector in two ways:
| Method | Best for | How to |
|---|---|---|
| UI | Fast setup without editing files | Go to Nodes → Configure this node → Collectors → Jobs, search for snmp, then click + to add a job. |
| File | If you prefer configuring via file, or need to automate deployments (e.g., with Ansible) | Edit go.d/snmp.conf and add a job. |
important
UI configuration requires paid Netdata Cloud plan.
Prerequisites
SNMP access
SNMP must be enabled on the device and reachable from the Netdata Agent acting as the site's SNMP hub.
Configuration
Options
Configure the SNMP collector with the device hostname and SNMP credentials. See the SNMP collector reference for all options.
via UI
Configure the snmp collector from the Netdata web interface:
- Go to Nodes.
- Select the node where you want the snmp data-collection job to run and click the ⚙ (Configure this node). That node will run the data collection.
- The Collectors → Jobs view opens by default.
- In the Search box, type snmp (or scroll the list) to locate the snmp collector.
- Click the + next to the snmp collector to add a new job.
- Fill in the job fields, then click Test to verify the configuration and Submit to save.
- Test runs the job with the provided settings and shows whether data can be collected.
- If it fails, an error message appears with details (for example, connection refused, timeout, or command execution errors), so you can adjust and retest.
via File
The configuration file name for this integration is go.d/snmp.conf.
The file format is YAML. Generally, the structure is:
update_every: 1
autodetection_retry: 0
jobs:
- name: some_name1
- name: some_name2
You can edit the configuration file using the edit-config script from the
Netdata config directory.
cd /etc/netdata 2>/dev/null || cd /opt/netdata/etc/netdata
sudo ./edit-config go.d/snmp.conf
Examples
There are no configuration examples.
Alerts
There are no alerts configured by default for this integration.
Metrics
On top of the generic SNMP baseline (the Generic SNMP Device integration — interfaces, system, IP/TCP/UDP, host resources), this Citrix Netscaler profile adds the metrics below. Each is collected only where the device exposes the matching OID — inclusion means the profile requests it; availability depends on the device model and software.
107 metrics in 11 groups; each row is a chart context usable in alerts.
