Scheduling of custom check to run once a day at certain time

Telegraf
1

I have a custom check that I only want to run once a day but at 12am or 12:01 exactly.
I know the .conf file can specify interval for 24h in inputs.exec section but i’m wondering at what TIME this is run if it is every 24 hours and how can I specify this if it isnt to my liking.

sh-4.2$ cat cch_cl_daily_txn_count.conf

[[inputs.exec]]
interval = “24h”
commands = [“python /etc/telegraf/scripts/cch_cl_daily_txn_count.py”]
timeout = “60s”
name_override = “cch_cl_daily_txn_count”

Hello @fliu_infor,
Welcome!
I believe you can just run telegraf --once using cron itself for the scheduling.

  1. If I go this route, then should i set the interval to 0 so that telegraf does not run the script automatically? Or would I disable it?

  2. I was able to get --test to work but not --once not sure why this is the case…
