No datas in the graph

[mohamed]

Dear colleague ,

I have always the problems to see the datas in the graph that I have configured in my cacti , please find the log concerning 2 different
SNMP oid for the same server (mms_gateway_1 ) , I can see the datas in the graph of cacti for the snmp_oid_880 but Not for the snmp_oid_886.
IT is strange because I have use dthe same templates and the same way to create the both graphs.Please find below the cacti.log fo the 2 different graphs , maybe it can help.

Can you please help me to fix this issue , thans a lot for your help





SNMP query for which I can see the datas ( the SNMP risponse from the remote server) in the graph.

Both queries seem to work. This can be deduced from the rrdtool update statement. There is valid data in both cases.
Assuming, that the poller runs even theses queries every 5 mins, please do

Code: Select all

rrdtool fetch <rrd file> AVERAGE

and post the last 10 lines to see, whether rrdtool update was successful

Hi Richard



Below the answers

We would need some more info:

- what OID is queried ?

1.3.6.1.4.1.18328.1.1.915.0

- would does an snmpwalk against this OID return?

./snmpwalk -c public -v 1 193.43.236.193:8161 1.3.6.1.4.1.18328.1.1.915.0
SNMPv2-SMI::enterprises.18328.1.1.915.0 = Counter32: 33402

- is this a GAUGE or a COUNTER?
GAUGE ( I have tested COUNTER too but without succes)

- what is the MAXIMUM defined for the failing data source?

1000000 ( I have tested other value but without succes)

- please perform an "rrdtool fetch <rrd file> AVERAGE" and post the last 10 lines of the outcome to see, whether data is stored and perhaps "only" graphing fails.

Ah, you're using a non-standard SNMP port 8161. You did configure this when setting up the DEVICE you're polling? Are you getting a red SNMP error on the upper left corner of the page?

- is this a GAUGE or a COUNTER?
GAUGE ( I have tested COUNTER too but without succes)

I cannot confirm. The output clearly states this is a Counter32. Take care when changing the Data Template: This will NOT change existing rrd files. Either use "rrdtool tune" or delete and re-create the file.

- what is the MAXIMUM defined for the failing data source?

1000000 ( I have tested other value but without succes)

This seems to be ok

- please perform an "rrdtool fetch <rrd file> AVERAGE" and post the last 10 lines of the outcome to see, whether data is stored and perhaps "only" graphing fails.

Ok, so no data was stored.

To sum up: Please check the ds.type of the Data Template as stated above. When running the poller, please wait for two polling cycles and perform a "rrdtool info" of the rrd file and post the first 20 lines

But you again set this to ds.type= GAUGE. As I mentioned above, from the snmpwalk it can be ssen that COUNTER is the correct ds.type.
You may change this using

Code: Select all

rrdtool tune <rrdfile> -d snmp_oid:COUNTER

Please run the poller for some polling cycles and post rrdtool fetch output like above
