Environment:
UIM 8.*
CDM 6.3
Ubuntu 16.*
Cause:
If "sysstat" is not installed in the Ubuntu server, the probe won't gather these metrics. This is a prerequisite.
Resolution:
step 1 :- apt install sysstat
step 2:- open "/etc/default/sysstat" using file editor and change ENABLED="false" to ENABLED="true"
vim /etc/default/sysstat
----
# Should sadc collect system activity informations? Valid values
# are "true" and "false". Please do not put other values, they
# will be overwritten by debconf!
ENABLED="true"
----
step 3:- Change the collection interval from from every 10 minutes to every 2 minutes from file "/etc/cron.d/sysstat".(or based on your requirement).
----
vim /etc/cron.d/sysstat
Change
5-55/10 * * * * root command -v debian-sa1 > /dev/null && debian-sa1 1 1
To
*/2 * * * * root command -v debian-sa1 > /dev/null && debian-sa1 1 1
