Project Notes
For FRU,TEMP,SYSTEM and SPU monitoring this plugin runs through the ContentsIndex and getting Name, Type and State (Temp,CPU,MEM-Use) for each element listed in there. Based on what u specified to monitor ( -W ) it will return what you want. For TEMP, SPU and SYSTEM is a definition of warning/crit max requierd. In FRU Mode it will only return any Module isnt fine (online). if a FRU is Offline, it will return the Offline-Reason, too (textual). Empty slots are ignored. In NETWORK mode, it will on first run store a ninimal file in /tmp, witch contains InOctets, OutOctets and Timestamp, what will be needed to calculate average speed on next run. It uses the Counter64 In/Out octets. NOTE: Nagios-User need access rights to save Performance-Data Temporary( /temp) and run a Ping- Precheck ( /bin/ping ) Feel free to contact me, if you have any improvement. 17.10.2016 --BUGFIX for calculation of Network speed --- 02.12.2016 -- Fixed Minor Bug and Help Output reported by uvznap --

Outstanding! (some ideas for improvements)
by uvznab, November 30, 2016
This saved me hours (if not days) of work.
It works perfectly on my SRX100H.

Few comments to consider as improvements:
1. One minor bug exist in SNMPGET(oid) where Version needs to check if it's a string and fix it: result = netsnmp.snmpget(oid, Version = 2 if options.version == "2c" else int(options.version), DestHost=options.host, Community=options.community, Timeout=800000, Retries=0)[0]
2. Help text should state SPU instead of CPU as a valid input for the -W switch
3. It should be noted that it is assumed that the Nagios service user has access to /bin/ping and /tmp/juniper_lastdata.txt (mine wasn't and it took me 2 hours to find out why nothing works). Chown those two files if you share the same situation as I do.
4. NETWORKS switch won't work if /tmp/juniper_lastdata.txt doesn't exist. Quick fix: touch /tmp/juniper_lastdata.txt
5. I started writing an extension to check the disk utilization, but it's taking me longer than expected. I'll post my addition if I get around to finishing it.

Again, AWESOME work! Thanks for this plugin.
