snmpcollector 4.03 includes the incorrect samplerate value in the QOS message and Breaks TOT threshold calculation
Example:
QOS Message for 1 min poll rate includes a samplerate of 1800 (This should be 60)
QOS Message for 5 min poll rate includes a samplerate of 9000 (This should be 300)
QOS Message for 10 min poll rate includes a samplerate of 18000 (This should be 600)
The incorrect samplerate is seen in DrNimbus and in the RN_QOS* table
snmpcollector smallest poll interval value defaults to 30 seconds
Release : 9.2.0
Component : UIM - SNMPCOLLECTOR
Add below key in snmpcollector probe's setup section via raw configure:
SMALLEST_POLL_INTERVAL = 1
Steps :
1. Deactivate probe
2. Open raw configuration of the probe in adminconsole.
3. Go to setup section
4. Add new key/value pair as shown below
5. Save the changes
6. Activate probe
Samplerate value in QOS Message for 1 min poll rate should now be 60
Samplerate value in QOS Message for 5 min poll rate should now be 300
Samplerate value in QOS Message for 10 min poll rate should now be 600
NOTE:
The samplerate value in the QOS message is stored in the database (RN_QOS_DATA_* tables) and not visible through USM reports.
Use the following queries to check the samplerate value for a given QOS and Device
1. Select a device the is being monitored by the snmpcollector probe.
2. Replace 'devicename' with any device being monitored by the snmpcollector probe and run the query to identify its table_id and RN_QOS_DATA_* table.
In this example we are using QOS_AVAILABILITY_AVAILABILITY monitor.
select table_id, r_table from s_qos_data where source = 'devicename' and qos = 'QOS_AVAILABILITY_AVAILABILITY'
3. Take the table_id and RN_QOS_Data_* table values and run the query below to check the samplerate column
To see current samplerate values:
select * from RN_QOS_DATA_#### where table_id = #### order by sampletime desc;
To see samplerate values prior to adding the SMALLEST_POLL_INTERVAL =1 snmpcollector key
select * from RN_QOS_DATA_#### where table_id = #### order by sampletime asc;
