ESensors Advanced Environmental Monitor EM32-Xe

Post by CSykes1 »

When will Nagios support the Advanced Environmental Monitor EM32-Xe? I asked about this last year and was told it was coming.

You can try this one:

https://support.nagios.com/forum/viewto ... 13#p199513

Please post the FULL output of these commands from your XI server:
- Note: Make sure to change ESENSORIP to the IP of your ESENSOR.

Code: Select all

curl -k -L 'http://ESENSORIP/index.html?em345678' -v
curl -k -L 'http://ESENSORIP/status.xml' -v
curl -k -L 'https://ESENSORIP/index.html?em345678' -v

Looks like they should both work technically.

Open the "/usr/local/nagios/libexec/check_em.pl" plugin in vi.

Code: Select all

vi /usr/local/nagios/libexec/check_em.pl
Type:

Code: Select all

:set ff?
and hit "Enter" to view the file format. Does it say "unix"?

It it says "dos", you will need to change the format by typing:

Code: Select all

:set ff=unix
save, exit, and test your plugin again.

Let us know if this helped. Thank you!

It seems like the plugin is working now... You are no longer getting the "-bash: /usr/local/nagios/libexec/check_em.pl: /usr/bin/perl^M: bad interpreter: No such file or directory" error.

Do you have any further questions or we can lock this topic?
