linux's Issues

Only exit code 0 for plugin check_cpu_temp

Hello bms8197,

Thanks and big up for the plugin.

An issue was encountered where the check exited with code 0 even if status was WARNING and CRITICAL (not checked UNKNOWN).

So, via command line the WARNING can be seen successfully but the exit code is still 0:

root@theflash /usr/lib/nagios/plugins # ./check_cpu_temp 
OK - CPU(s) temperature(s): 44°C 47°C; high=79.0; crit=89.0

root@theflash /usr/lib/nagios/plugins # ./check_cpu_temp -w 40 -c 70
WARNING - CPU(s) temperature(s): 44°C 47°C; high=40; crit=70

root@theflash (NEW) /usr/lib/nagios/plugins # echo $?
0

The issue is that one will not be alerted if the threshold is reached or exceeded. The check will always remain green and display OK.

Server Specs:

Virtualization Technology: Proxmox
Architecture:        x86_64
CPU op-mode(s):      32-bit, 64-bit
CPU(s):              40
Vendor ID:           GenuineIntel
Model name:          Intel(R) Xeon(R) Silver 4114 CPU @ 2.20GHz

root@theflash /usr/lib/nagios/plugins # uname -a
Linux theflash 5.0.21-2-pve #1 SMP PVE 5.0.21-6 (Fri, 27 Sep 2019 17:17:02 +0200) x86_64 GNU/Linux

I have manually forced the exit code at STATUS check:

    # print statuses + output
    if status == OK:
        print("OK - " + output)
        exit(0)
    elif status == WARN:
        print("WARNING - " + output)
        exit(1)
    elif status == CRIT:
        print("CRITICAL - " + output)
        exit(2)

except Exception as e:
    print e
    status = UNK
    exit(3)
    raise

However, I dont think its clean code but it works. Can you check and possibly update the check with necessary the code?

Cheers,
Sarvesh.
