Hi
We would like to see a closer look at the bit rate of the network switches.
Is there a way to change the SNMP polling cycle time per element?
We would like to display a value that is a little closer to the current state, not only the bit rate but also the up/down status, etc.
Hi Yuki
You can change the polling speed of an element by changing the [Timer base] general parameter of that element. If you set the element’s [Timer base] parameter to 3, the frequencies of the timers will all be multiplied by 3. This will result in a slower polling speed. Entering a value < 1 will result in a faster polling speed.
To find the [Timer base] general parameter:
- Open the relevant element card.
- Go to the page General parameters.
- Enter the desired value next to [Timer base] and click the green check mark icon.
Detailed info about this topic can be found on docs.dataminer.services.
Hope this will help you out.
Kind regards
Do note that we are always trying to select the best possible timer intervals based on all known criteria. For example, if you use [Timer Base] to speed up the polling interval, this could for example overload the SNMP agent of your product.
Hi Yuki,
You could use the timer base parameter to update the polling cycle per element. You can find this parameter in the General Parameters page. Please keep in mind the following:
- This setting will affect all the timers defined in the connector
- Since you are polling faster your network switch, you will need to verify that this action will not affect the device's performance
- This action also has an effect on the DMA. There could be a negative impact on some DataMiner processes (SLScripting, SLProtocol)
Regarding the counters available in the IF table and IFX table (that are used to calculate the bit rates), before to start modifying the polling speed, it will be good to know how often the switch is updating the counters. For example, if the switch update the counters every 30 seconds, updating the element to poll these counters faster than 30 seconds will not make any difference.
And regarding the IF operational state (up/down status), instead of polling faster the the IF table, I believe it will be a good idea to use the the SNMP traps Link Up/Link Down to update the operational state.
Thanks for the pertinent response.
