Apache_up shows 0 even my apache_exporter is on about apache_exporter

[Lusitaniae]

I misread your question.

It seems the exporter couldnt connect to Apache.

Do you see any errors when you run the exporter in the command line?

You need to enable server-status handler for Apache to report data. This is the most frequent issue.

You should be able to read Apache data on this url localhost/server-status?auto by defalt

See the previous discussion at #29 (comment)

HI @janeunbi

Is it working now?

[janey-day]

hi @Lusitaniae
Thank you for your reply
nope it doesn't work, I can see the all metrics provided.
I can't understand why value of apache_up comes out 0 even the apache_exporter and apache still working on.

hi @janeunbi

You're missing all the Apache metrics except for apache_up with reports as 0.

Can you run curl localhost/server-status?auto on the server and share the result?

This is the url the exporter is trying to get metrics from.

Here's my all the Apache metrics and apache_up status behind the chart.

Through this, I can figure it out its metrics works except apache_up metric

[Lusitaniae]

Look at the read me, there’s more metrics than that, can you check the other things I asked above?

Sorry I forgot to attach the files.
I don't know which server I should run "curl localhost/server-status?auto ", so I typed it both prometheus server and web server which installed apache_up.
Here's the pic of prometheus server.

This one is installed apache_up.

[Lusitaniae]

the command is meant to retrieve the status page from Apache itself, so running it in the same machine as apache is the right one.

Looking at that 301 redirect you show on the 2nd screenshot I'd say the rewrite rule you use to enforce https is not working as expected, as you can see there's a slash missing there.

Please also check you have all the configuration required, as described in the official docs.

https://httpd.apache.org/docs/2.4/mod/mod_status.html

<Location "/server-status">
    SetHandler server-status
    Require host example.com
</Location>

or follow a more detailed guide such as

Thank you for trying to help me.
I read your comment over and over, not sure I'm in the right direction.

1. Which one is 301 redirect? Where is the slash missing?
2. you mean "https" causing this problem, am I right?
3. To fix this problem, I need to enable Apache Server Status Page and should make or edit configuration file in the Web server.

p.s. I'm not sure I understand what you said. Unfortunately, web server is belong to my work, I don't think I able to fix that file.
Thank you again

@janeunbi, maybe its possible someone else at your company have a look at this?

If the Apache config needs to be fixed to make it work, there's no other way around it.

[Lusitaniae]

hi @janeunbi

Is this still an issue?

Is there anything I can help with?

[Lusitaniae]

I will close the issue unless you need additional feedback here.

In case you dive into this further, the answer to your questions

1. the redirect is seen on the 2nd screenshot you've sent
2. Can be, there's a redirect rule somewhere that is causing the missing slash-
3. yes, you need to review the web server config.
