SNMP V2 Data Query

[sforsythe]

Referencing this old post, was very close to exactly what I needed, but still having issues
http://forums.cacti.net/viewtopic.php?f=21&t=43860
I am using Cacti 0.8.8a , on CentOS6.4

Here is my xml

Code: Select all

<interface>
   <name>Get IPRS Statistics</name>
   <description>Queries for Kemp IPRS statistics</description>
   <oid_index>.1.3.6.1.4.1.12196.12.2.1.1</oid_index>

   <fields>
      <iprsIndex>
         <name>Index</name>
         <method>walk</method>
         <source>index</source>
         <direction>input</direction>
      </iprsIndex>

      </iprsBytesOut>
   </fields>
</interface>

Note in the previous thread , it was suggested to use

<iprsIndex>
<name>Index</name>
<source>value</source>
<direction>index</direction>
</iprsIndex>

but I changed source:value to source: input as that seemed to be suggested here http://www.cacti.net/downloads/docs/htm ... y_xml.html , and added a Method: walk , as while during debug that seemed to be an error.

1. I create a new data query

Name: kemp
Description: kemp
XML Path: <path_cacti>/resource/snmp_queries/kemp2.xml
Data Input Method: Get SNMP Data (Indexed)

Get: "Successfully located XML file:

2. Create new device

Downed device Detection: SNMP Uptime
SNMP Version: 2
SNMP Community: public
SNMP Port: 161
SNMP Timeout: 5000
Max OID per get request: 10

Upon save, device is created, and successfully SNMP polled (shows SNMP Information on device screen)

3. Add Data Query to device

Status: Success (184 items, 92 Rows)
Verbose Query: (truncated, not showing all 92 rows )
+ Running data query [24].
+ Found type = '3' [SNMP Query].

...
+ Found item [iprsDesc='10.10.1.223:80 Masq 0'] index: 92 [from value]

... Looks Great so far

4. Add a Data Template

Data Template
Name: Kemp
Data Source
Name: |query_iprsDesc| - Bytes (check user per-data source value)
Data Input Method: Get SNMP Data (Indexed)
Data Source Active: Check
Data Source Item:
Internal Data Source Name: BytesOut
Min Value: 0
Max Value: U
Data Source Type: Counter
check "user per-data source value" for Index Type, Index Value, Output Type-ID

5. Create graph template

Title: |query_iprsDesc| - BytesOut
Use per-graph value checked

Added 1 Graph Template Item
Data Source: Kemp - (iprsBytesOut)

Graph Item Inputs shows:
Data Source [iprsBytesOut]

6. Data Queries -> Assocated Graph Templates -> Add

Name: kemp
Graph Template: kemp
check data source for iprsBytesOut
Add suggested Values
Data Template: BytesOut - |query_iprsDesc| --> Name
Graph Template: BytesOut - |query_iprsDesc| --> Title
save


7. I goto the device, "create graphs for this Host"

Capture.PNG (40.99 KiB) Viewed 1265 times

I select any random one, hit create

If we look at the graph, it doesn't seem to be populating the query_iprsDesc value

Capture3.PNG (29.83 KiB) Viewed 1265 times

The same with the data source name, and if we look at details of the data source , it has no index value assigned

Capture4.PNG (79.77 KiB) Viewed 1265 times

If we look at devices

Capture5.PNG (11.78 KiB) Viewed 1265 times

We see there is one graph and one data source assigned, but status remains unknown, and no matter what level of debug I use, nothing in the Logs ever suggests it even looks at this host/data source on polling.


If I add any other standard data source (interface network traffic), the device is polled and a graph is generated for that data source, but nothing occurs for the other graph data source (missing rra and graph image)

The difference is snmp -v2c ... any suggestions on how to debug and find out why it is not firing?

Given the appearance of the simple single valued index, I wouldnt recommend using the <oid_index_parse> stuff. It just further complicates things unnecessarily. Looking at the verbose output of the kemp2.xml, the index values do appear wrong too.

I only used one value for simplicity ... there are actually 4 values I will need

Code: Select all

+ Index found at OID: '1.3.6.1.4.1.12196.12.2.1.1.1' value: '0'
+ Index found at OID: '1.3.6.1.4.1.12196.12.2.1.1.2' value: '0'
+ Index found at OID: '1.3.6.1.4.1.12196.12.2.1.1.3' value: '1'
...
+ index_parse at OID: '1.3.6.1.4.1.12196.12.2.1.1.1' results: '1'
+ index_parse at OID: '1.3.6.1.4.1.12196.12.2.1.1.2' results: '2'
+ index_parse at OID: '1.3.6.1.4.1.12196.12.2.1.1.3' results: '3'

As I understand it, this is getting index = 1,2,3

There is not an OID that has "index" values, that is why I have to parse the OID itself. The first 4 lines above are showing the correct values for those OID's (0,0,1)

Running the following manually gives
php cmd.php 77 877
POLLER: Poller[0] NOTE: There are no items in your poller for this polling cycle!

But there ARE graphs created for this device, there ARE data sources for device, etc ....

I've tried putting down to SNMP v1, no difference. Any suggestions on how to fix?

[BSOD2600]

anything in the poller cache for this device? Try rebuilding it.

you been messing around with 1 min polling per chance?

[sforsythe]

There is no entry being generated for poller item ... is this a bug of using OID PARSE?

If I manually generate a poller_item entry in db using sql query ..... a graph now shows up!

I don't want to have to do that for 92 entries though

Nor should you have to.

Try deleting the data sources/graphs from this device for your Data Query so you're starting from a clean slate. From the 'create graphs for this host' screen, recreate the various items you want. Now check the poller cache if the items have been added. No errors in the cacti.log during this process?
