OneAgent does not see haproxy (socket mode stats)

Hello!

What can be reason for ignoring v1.7.9 haproxy?

We are setting up haproxy socket monitoring mode.

As per https://www.dynatrace.com/support/help/technology-support/monitoring-support/haproxy/

- Dynatrace User (dtuser) with read privileges in the HAProxy configuration file - OK

- Dynatrace User (dtuser) with read/write privileges in stats sockets - OK

- Stats socket located in a directory in which Dynatrace User (dtuser) has execute permissions -OK

- No docker. Haproxy is regular Linux process.

We sudo to dtuser and under dtuser agle to get stats from it by command

echo "show stat" | nc -U /var/run/haproxy/process1.sock

What else to check?

Regards,

Igor

Hi,

Do you have any info in the haproxy error log? Or in oneagent logs?

What rights does the dtuser has? 600 ? 766?

Ok after 1) setting correct number of sockets = number of workers 2) and disabling admin socket it started to work

now i wonder what is wrong with admin socket and why it it not ignored then marked by #DYNATRACE.SKIP line

Hello

Haproxy help https://www.dynatrace.com/support/help/technology-support/application-software/other-technologies/ha...

mentions OneAgent v1.165 in "Skipping admin socket" section.]

But in Managed env i only have v1.163 OneAgent.

When will v1.165 agent available for Managed environment?


New version is appear each month.

I think we can expect it in the end of April.

I also wait it 😉 (need Akka Http client support)
