Setting Polling Frequency for a Device Group

You can set global or individual polling frequency for an extended device group. You do so by specifying a polling frequency modifier. This is a coefficient by which the default NetMRI setting is multiplied. The higher the coefficient, the more frequently devices in the current group are polled.

Note

Setting a custom polling frequency may affect performance. High modifier coefficient results in polling performed more frequently, so the NetMRI unit may be more busy than usual.


The default NetMRI polling frequency is located in Settings icon > Setup > Device Collection Status. The global polling frequency modifier is located in Settings icon > General Settings > Advanced Settings – Data Collection > Polling Frequency Modifier.

You can set values between 0.5 and 2 for the global or group-level polling frequency modifier. Interpret the values as follows:

  • 0.5: Makes polling twice slower.
  • 1: Means same polling frequency as the default setting.
  • 2: Makes polling twice faster.

As NetMRI recalculates polling frequency every 10 minutes, the new polling frequency is applied to the group not later than 10 minutes after you specified it.

The polling frequency modifier affects SNMP credentials guessing. For example, by default it happens once a day. With the polling frequency modifier, you can make it happen twice a day or once in two days. This setting does not affect the frequency of CLI credentials guessing or config collection.

To set polling frequency for a device group, complete the following:

  1. Click the Settings icon > Setup > Collection and Groups > Groups.
  2. Click Add for a new group or open an existing extended device group for editing.
  3. In Polling Frequency, select one of the following:
    • Use Global Settings: Select this to enable the device group to inherit the global polling frequency modifier setting.
    • Specify Polling Frequency: Allows you to set individual polling frequency for the current device group. 
      If you select Specify Polling Frequency, the Polling Frequency Modifier field appears.

  4. In the Polling Frequency Modifier field, specify the coefficient that modifies the device group polling frequency relative to the default NetMRI setting.

Note

Currently, the polling frequency modifier does not apply to SDN devices as they use a different polling engine.
