NetEye 4 is a comprehensive monitoring platform which natively supports Icinga 2 checks on remote hosts and devices.
Several Icinga 2 checks support an historical view of the status. An example is the firewall interface performance status below, which displays a Performance Graph:
All the graph data generated by the Icinga 2 checks are hosted by default in a local Influx database named “icinga2”. This is very useful for rendering the collected metrics using the Grafana engine in NetEye’s ITOA.
First of all, a new Datasource must be defined in ITOA. The Datasource could be of type INFLUX/QL or Flux and requires a read-only account to access the “icinga2” Influx DB:
This new Datasource can then be used to create Grafana dashboards.
The next question is: how is the collected data named in the “icinga2” database?
The answer is that metrics use the Icinga 2 command name. In the firewall example above, the Icinga 2 command is called “nx-c-check-nwc-health”:
We recommend that the Grafana variable holds the host to be rendered, as in this example:
This way, the dashboard can be reused for different hosts just by changing the Regex field in the variable definition. Thus an Influx-QL query sample to get the firewall graphs of all the firewall interfaces, which uses the host variable defined above, becomes:
SELECT max("value") FROM "nx-c-check-nwc-health" WHERE ("hostname" =~ /^$host$/) AND ("service" =~ /Traffic Interface/) AND $timeFilter GROUP BY time($__interval), "service" fill(null)
When this query is rendered as a Grafana panel it produces this dashboard:
In a single dashboard you can see the traffic of all the firewall interfaces with the max value in the selected time period.
Icinga 2 graphs are useful not just for network performance, but also for host monitoring. The example below is an ITOA dashboard which monitors vSphere infrastructure performance and also shows the VMware datastore allocation over the time period.
Icinga 2 monitoring is very powerful: with ITOA and the Grafana engine, you can make dashboards even more useful!
