Hello everyone,

I had to change the login credentials for my HAProxy (user stats insecure-password XXX).

Unfortunately ClusterControl is not able to collect performace datas anymore.

time="2020-01-15T15:43:36+01:00" level=error msg="Can't scrape HAProxy: HTTP status 401" source="haproxy_exporter.go:315"

How and where can I change the scrape-uri parameters for the HAProxy exporter process?

 

Thank you in advance

Leo

  Hi,

  You can change the URL used by the haproxy_exporter:

  

  I the example above I've changed the password for the user 'admin' to 'admin222'.

  Perfect,

  thank you very much!

  Got it working now but run into a couple of problems.

   

  1. --haproxy.scrape-uri=http://proxy:admin222@10.10.0.151:9600/haproxy?

  For me the exporter is not able to parse the output from the status page.

  time="2020-01-16T14:16:32+01:00" level=error msg="Parser expected at least 33 CSV fields, but got: 1" source="haproxy_exporter.go:372"
  time="2020-01-16T14:16:32+01:00" level=error msg="Can't read CSV: line 1349, column 10: bare \" in non-quoted-field" source="haproxy_exporter.go:334"

   

  2. --haproxy.scrape-uri=http://proxy:admin222@10.10.0.151:9600/haproxy?stats;csv

  Seems that the deployment script has a problem with the semicolon. I created a job loop with this version.

    .

    10.10.0.151: Command was cd /var/lib/prometheus
    export PATH=/usr/local/bin:/usr/bin:/bin:$PATH
    export HOME=/var/lib/prometheus
    nohup daemon --name=haproxy_exporter_9102 --inherit --output=/var/log/prometheus/haproxy_exporter_9102.log --env="PATH=/usr/local/bin:/usr/bin:$PATH" --chdir=/var/lib/prometheus --pidfile=/var/run/prometheus/haproxy_exporter_9102.pid --user=prometheus -- haproxy_exporter --haproxy.scrape-uri=http://proxy:admin222@10.10.0.151:9600/haproxy?stats;csv --web.listen-address=":9102" .

   

  3. --haproxy.scrape-uri="http://proxy:admin222@10.10.0.151:9600/haproxy?stats;csv"

  This one finaly worked for me.

   

  The next problem I had was the length of the haproxy exporter arguments list. If it is too long, the cross for deleting the string is not showing up anymore. Tested it with Firefox and Chromium.I had to shorten the string in the browser devolement tools to see the cross again.

   

  Just for the case, someone is running into the same problem.

  Thank you for your help!

  Greetings

  Leo

  Hi Christian,

   

  Can you provide a screenshot of what you got there? Also what version of ClusterControl you are using?

  Hi Paul,

  sure!

  Controller: 1.7.4.3596, Frontend: 1.7.5.6604-#f665d5,

  As you can see on the screenshot only the lower argument list on marker 1 has a cross for deletion. The other two strings are not deletable.
