[inputs.sysstat] Collection took longer than expected; not complete after interval of 1s

1

In an environment using the following version of TelegrafAgent, when setting up the performance information acquisition at one second intervals, error messages are repeatedly output to /var/log/messages and some performance information acquisition is missing. We would like to know how to solve this problem as soon as possible.

■Environment in which the problem occurred
OS: Red Hat Enterprise Linux 8.8
Version used: 1.27.3
Error message: [inputs.sysstat] Collection took longer than expected; not complete after interval of 1s

Just use a higher interval, if the system + Telegraf can’t respond fast enough there is not much you can do.

the interval can be set higher as a whole (agent settings), or be overridden for each single input plugin

[agent]
  interval = "10s"

[[inputs.___]]
  Interval = "5s"
  {...}

[[inputs.___]]
  Interval = "20s"
  {...}

Thank you for your response.

Since the only information telegraf obtains is performance information, and only from sysstat, we do not believe that it would be possible to obtain this information even if it were limited to sysstat.

I feel that the information described in the following URL may improve the situation, but I do not understand much of the content and would appreciate your advice on the detailed settings in this area.
