Template Best practice for HP PDUs

[Jan Scholten]

I am not really understanding the "regular" documentation, but Gandalfs Howto helps a bit, but i am not sure, whether this is the "best" or "most efficient" way.

So here is what i would like to do:
I am trying to monitor HP Power Distribution Units with Power Monitoring Model number is S2132.
It is a multiple socket outlet (?) with monitoring abilitys.

This PDU has a LAN interface and can be queried by snmp (and http aso. but this is irrelevant now)

It is internally divided into two PDU (for each "external 3 Phase 16A" connector) so behind each IP is a PDU A & a PDU B.

an SNMP Walk shows following interesting stuff (things i want to monitor):

Code: Select all

SNMPv2-SMI::enterprises.232.165.2.3.2.1.2.1.1 = Voltage Segment 1 PDU A 
SNMPv2-SMI::enterprises.232.165.2.3.2.1.2.1.2 = Voltage Segment 2 PDU A 
SNMPv2-SMI::enterprises.232.165.2.3.2.1.2.1.3 = Voltage Segment 3 PDU A 

SNMPv2-SMI::enterprises.232.165.2.3.2.1.3.1.1 = Current Segment 1 PDU A
SNMPv2-SMI::enterprises.232.165.2.3.2.1.3.1.2 = Current Segment 2	PDU A
SNMPv2-SMI::enterprises.232.165.2.3.2.1.3.1.3 = Current Segment 3	PDU A

SNMPv2-SMI::enterprises.232.165.2.3.2.1.4.1.1 = Load Segement 1 in % PDU A
SNMPv2-SMI::enterprises.232.165.2.3.2.1.4.1.2 = Load Segement 2 in % PDU A
SNMPv2-SMI::enterprises.232.165.2.3.2.1.4.1.3 = Load Segement 3 in % PDU A

SNMPv2-SMI::enterprises.232.165.2.3.2.1.2.2.1 = Voltage Segment 1 PDU B 
SNMPv2-SMI::enterprises.232.165.2.3.2.1.2.2.2 = Voltage Segment 2 PDU B 
SNMPv2-SMI::enterprises.232.165.2.3.2.1.2.2.3 = Voltage Segment 3 PDU B 

SNMPv2-SMI::enterprises.232.165.2.3.2.1.3.2.1 = Current Segment 1 PDU B 
SNMPv2-SMI::enterprises.232.165.2.3.2.1.3.2.2 = Current Segment 2	PDU B 
SNMPv2-SMI::enterprises.232.165.2.3.2.1.3.2.3 = Current Segment 3	PDU B 

SNMPv2-SMI::enterprises.232.165.2.3.2.1.4.2.1 = Load Segement 1 in % PDU B 
SNMPv2-SMI::enterprises.232.165.2.3.2.1.4.2.2 = Load Segement 2 in % PDU B 
SNMPv2-SMI::enterprises.232.165.2.3.2.1.4.2.3 = Load Segement 3 in % PDU B 

SNMPv2-SMI::enterprises.232.165.2.3.1.1.3.1 = Total Heat PDU A in BTU
SNMPv2-SMI::enterprises.232.165.2.3.1.1.4.1 = Total Power PDU A in Watt

SNMPv2-SMI::enterprises.232.165.2.3.1.1.3.2 = Total Heat PDU B in BTU
SNMPv2-SMI::enterprises.232.165.2.3.1.1.4.2 = Total Power PDU B in Watt

SNMPv2-SMI::enterprises. is 1.3.6.1.4.1. so the OIDS are
1.3.6.1.4.1.232.165.2.3.2.1.2.1.1
All values are integers btw.

Now I'd like to create templates so that for more PDUs i just have to enter an IP and *magic* all Graphs are created.. *g*

So i started with creating an "Get SNMP Data" Data Template for each and every line (see above).

After that i created Graph Templates for Voltage, Current, Load .. so each goes in one Graph, ... after that i created a host Template and added Voltage, Current and Load Graphs to it. BUT i don't now what i should choose at associated Data querys.. as i have none-- i guess i don't add any?

Which way would the experienced User try to accomplish my task?


Last question:
Would it be betterto use "Get SNMP Data (indexed)" If so what do i need to specify in the xml? Or is it not possible at all?
I thought it might be cleaner/faster (as it can query all data in on run?)

Which way would the experienced User try to accomplish my task?

If the device gives you an index count, then you can use the 'Get SNMP Data (indexed)' method for acquiring data (like the snmp interface template & \resource\snmp_queries\interface.xml). If it doesn't then I'd use the PHP script server to query the OIDs and return their data (like the snmp partition template & \scripts\ss_host_disk.php)

I've got additional examples of both methods in my signature for the various scripts.

I am not really sure what an indexed count is, so i guess no it does not

I will have a look at your scripts though.. thanks.

[BSOD2600]

an index is a number which represents the count of something. For example, on Interfaces, there is a number (ifIndex), which represents each unique interface on a device. Go ahead and run the following on a snmp enabled device to see what I mean: snmpwalk -v 1 -c public 127.0.0.1 ifEntry.

That enables cacti to uniquely collect data from a specific interface and also investigate how many a device has (also because it uses the number returned from ifNumber). But I degrees. If your HP device doesn't give a unique index number for each umm PDU, then you have to hard-code the snmp queries to the specific OIDs which the device has.

The sloppy way would be to create a dozen data templates, each specifying a single OID. the better way is to create a script utilizing the PHP script server, which queries all of those OIDs at once.

[Jan Scholten]

I did it the first way (creating lots of Data Templates) as this was the easiest way, and the presentation is on Friday.. will have a look for the script server thingy later, 12 PDUs give my about 200 rra..
I am a interested if cacti will work when i start monitoring 200+ Cisco Routers..

Yup, no problem.

Check out the announcement forum for metrics of others giant cacti installations.

I am working on template for this now. Did you ever complete it?

Your templates are very welcome.
Would you mind publishing them at the 4th link of my sig? This is the official Cacti Template repository and we'd love to see your results there

Having trouble getting a MIB for HP PDU's. Endless hassle from HP rep getting one. If anyone has one, please post, and I can get a lot further with this project.

Yes I will for sure post them to the official template page.
