Hi all,

I'm trying to monitor a web page and I want to search for the word "Summary" but I am getting an error. "(No output on stdout) stderr: /bin/sh: -c: line 0: unexpected EOF while looking for matching `"'"

I've tried both Regex and Web Page Content. What am I doing wrong?

Hi @kbauma01, thanks for reaching out.

We could use a little more information, to try and help you sort this out. What version of XI are you using and what OS distro & version?

Also, what Wizard or plugin (check_) are you using?

DOH! I should have added more info.

XI 20241.1.3
Red Hat 8.9

I'm using the Website Configuration Wizard. Ping works, but https checks and searching for a word does not.

But if I run it manually in the CCM, I get this:

[nagios@nagserver ~]$ /usr/local/nagios/libexec/check_http -H myserver1.domain -f follow -I 192.1.1.1 -u "/" -S --sni -p 443 -a "user:password"
HTTP OK: HTTP/1.1 200 OK - 18629 bytes in 0.084 second response time |time=0.083907s;;;0.000000 size=18629B;;;0

It looks like there might be a problem with how the quotes are being used in your command. Make sure the quotes are properly matched and any special characters are escaped. For example, if you're searching for the word "Summary" with quotes, your command might look like grep "\"Summary\"". If you can provide more details about your command, I can help you troubleshoot further.

I ran both the Website and Website URL wizard. I put "Summary" in the Web Page Content field and for the Web Page Regular Expression field I have "\"Summary\""

They still fail.

OK, I deleted the services checks and the host and ran the website wizard again. Everything but the regex check is OK. The word I am looking for is Orion, is this the correct regex?

-r ""\"Orion\"""

And it's working. I removed the two \'s and it is good.

-r """Orion"""

Thanks for the help!

Glad the solution has been found and the fix is in the regex. I'm going to go ahead and lock this issue since the solution has been found. If you run into anything else feel free to reach out.
