Issue/Introduction
Nic metrics have been enabled but none are being generated and confirmed this via DrNimBUS and the probe log.
Environment
Release : 20.4
Component : UIM - CDM WITH IOSTAT
Resolution
cdm uses the sar command to get NIC info.
The command has to work for cdm to produce nic metrics.
This command can be used to test for Linux OS nic support:
sar -n DEV | grep 'Average:' |awk '{ print $2}' | grep -vwE 'lo'
example of it working:
[root@xx2072 ~]# sar -n DEV | grep 'Average:' |awk '{ print $2}' | grep -vwE 'lo'
eth0
virbr0-nic
virbr0
example of it failing:
[root@xx2072 ~]# sar -n DEV | grep 'Average:' |awk '{ print $2}' | grep -vwE 'lo'
Invalid system activity file: /var/log/sa/sa22
File created by sar/sadc from sysstat version 10.1.5
Current sysstat version cannot read the format of this file (0x2171)
Or if sar is not loaded.
Additional Information
In the log this starts the section on nic:
