Monitor Hosts

The NetQ Agent is supported on the following Linux hosts:

  • CentOS 7
  • Red Hat Enterprise Linux 7.1
  • Ubuntu 18.04

You need to install the NetQ Agent on every host you want to monitor with NetQ.

The NetQ Agent monitors the following on Linux hosts:

Using NetQ on a Linux host is the same as using it on a Cumulus Linux switch. For example, if you want to check LLDP neighbor information about a given host, run:

cumulus@host:~$ netq server01 show lldp
Matching lldp records:
Hostname          Interface                 Peer Hostname     Peer Interface            Last Changed
----------------- ------------------------- ----------------- ------------------------- -------------------------
server01          eth0                      oob-mgmt-switch   swp2                      Thu Sep 17 20:27:48 2020
server01          eth1                      leaf01            swp1                      Thu Sep 17 20:28:21 2020
server01          eth2                      leaf02            swp1                      Thu Sep 17 20:28:21 2020

Then, to see LLDP from the switch perspective:

cumulus@switch:~$ netq leaf01 show lldp

To get the routing table for a server, run:

cumulus@host:~$ netq server01 show ip route
