Kemarin saya sedang mencoba menambahkan plugin check_apc ke nagios untuk memonitoring UPS APC 2000V yang ada di ruang server, monitoring nya sebenar nya berbasis SNMP Oid dan sudah ada yang membuat script nya di https://exchange.nagios.org/directory/Plugins/Hardware/UPS/APC/Check-APC-UPS/details
namun ketika mencoba mengeksekusi script perl nya terdapat error
root@serveraldy:~# /usr/local/nagios/libexec/check_apc.pl
Can't locate Switch.pm in @INC (you may need to install the Switch module) (@INC contains: /etc/perl /usr/local/lib/perl/5.18.2 /usr/local/share/perl/5.18.2 /usr/lib/perl5 /usr/share/perl5 /usr/lib/perl/5.18 /usr/share/perl/5.18 /usr/local/lib/site_perl .) at /usr/local/nagios/libexec/check_apc.pl line 22.

root@serveraldy:~#nah dari error di atas dapat di ketahui di server nagios saya belum ada modul ‘switch.pm’ di perl nya maka kita bisa install modul tersebut lewat CPAN , CPAN singkatan dari (Comprehensive Perl Archive Network) adalah Repositori yang berisi 200.118 Modul dari 36.414 distribusi perangkat lunak yang ditulis dalam bahasa pemrograman Perl yang dikembangkan oleh 13.505 kontributor dari seluruh dunia. Perangkat lunak yang ada di CPAN adalah Perangkat lunak bebas dan kode sumbernya terbuka. berikut langkah nya
oot@serveraldy:~# cpan
CPAN.pm requires configuration, but most of it can be done automatically.
If you answer 'no' below, you will enter an interactive dialog for each
configuration option instead.
Would you like to configure as much as possible automatically? [yes] yes
Autoconfigured everything but 'urllist'.
Now you need to choose your CPAN mirror sites. You can let me
pick mirrors for you, you can select them from a list or you
can enter them by hand.
Would you like me to automatically choose some CPAN mirror
sites for you? (This means connecting to the Internet) [yes] yes

Autoconfiguration complete.
commit: wrote '/root/.cpan/CPAN/MyConfig.pm'
You can re-run configuration any time with 'o conf init' in the CPAN shell

cpan[1]>nah ketika muncul shell cpan nya bisa kita install module swicth.pm dengan mengetikan ” install Switch ” dan exit ketika sudah selesai

root@serveraldy:~# kemudian saya coba eksekusi lagi file check_apc.pl nya dan script nya running.
root@serveraldy:~# /usr/local/nagios/libexec/check_apc.pl
/uslocal/nagios/libexec/check_apc.pl - v2.2
Nagios script to check status of an APC Symmetra Uninteruptable Power Supply.
Usage:
-H Address of hostname of UPS (required)
-C SNMP community string (required)
-l Command (optional, see command list)
-p SNMP port (optional, defaults to port 161)
-t Connection timeout (optional, default 10s)
-w Warning threshold (optional, see commands)
-c Critical threshold (optional, see commands)
-h Use High Precision values for InputVoltage/OutputVoltage/OutputCurrent
-u Script / connection errors will return unknown rather than critical
Commands (supplied with -l argument):
id

out_freq
The current output frequency of the UPS system in Hz
** NB: thresholds must be expressed in range as nearest values. ex: normal=50, warning=45:55, critical=40:60 **
out_load
The current UPS load expressed in percent of rated capacity
