Telegraf output prometheus lose precision

have a telegraf with a external script to grab potential aws ec2 instance termination

  interval = "10s"
  round_interval = true
  metric_batch_size = 1000
  metric_buffer_limit = 10000
  collection_jitter = "0s"
  flush_interval = "10s"
  flush_jitter = "0s"
  precision = ""
  debug = false
  logfile = "/var/log//telegraf/telegraf.log"
  quiet = false
  hostname = "backuppc-a01"
  omit_hostname = false

  listen = ":9009"

  # get termination time
  commands = [ "/usr/local/sbin/" ]
  data_format = "influx"
  timeout = "15s"

$ /usr/local/sbin/ 
aws_instance_termination,action=instance-stop,host=backuppc-a01 seconds=1192060i

yet curl tp telegraf output this:

aws_instance_termination_seconds{action="instance-stop",host="backuppc-a01",id="backuppc-a01",region="eu-central-1",type="t3.micro",zone="eu-central-1a"} 1.19206e+06

Notice the integer to float, something with a seconds precision gets rounded to several minute with the same value

This outputs in prometheus a step that breaks alerting

Notice that the graph is always this, if i wait 10min, i still get the same graph, where was flat turns back to the same angled line

I tried to change the script output to integer, uinteger, float and i’m unable to fix this.

Any hint how to fix or workaround this? right now the only way i can see is to increase the prometheus alert range to outside the step, so it can always change

thanks for the help

Ok, after looking to this again, i changed my mind, i don’t see the lost of precision bin the integer to float, i assumed a wrong problem based on a wrong number of samples
Doing periodic curls to telegraf, i do not see any problem in the output. So for sure my problem isn’t in the telegraf

if i check the ALERTS{alertname=“Instance_Termination_Long”}, that show this alert, i do not see any problem in prometheus alert to justify the flapping alert.
So while that first 5 minutes step in prometheus is very weird, i now think the problem i’m having is really a alertmanager problem.

So sorry about the noise
