  • Probe Scalability

Interface count

We recommend monitoring up to 10,000 interfaces per probe.

Trap processing limit

To avoid any performance degradation in OpManager MSP probe, the number of traps to be processed per hour is limited to a maximum of 50,000. If this threshold is breached, the probe stops processing traps for a temporary period.

For versions below 128398:

Given below is the maximum advisable number of monitors for a single probe, when monitoring 1,000 devices,

For versions 128398 and above:

Given below is the maximum advisable number of monitors for a single probe, when monitoring up to 2,500 devices.

*A rate of 500 polls per minute is only recommended when using the "Windows Native API based Availability Monitoring (ICMP dll)" protocol for availability monitoring. For other protocols, a rate of 300 polls per minute is recommended.

Monitoring best practices:

  • Adding more monitors than the numbers suggested below will directly impact the performance of OpManager MSP probe.
  • If it is required to add more monitors, then the polling interval of that monitor must be increased accordingly in order to balance the load on the OpManager MSP probe server.
  • Adding monitors with more than 100 instances will indirectly affect the performance of OpManager MSP probe.
  • Follow the below recommended polling intervals for optimal performance:
    • Availability Monitors: 5 minutes
    • Performance Monitors: 10 minutes
    • Interface Performance Monitoring: 15 minutes

Syslog processing limit

A rate of 200 Syslogs per probe every 2 minutes is recommended to avoid any impact on product performance.

NetFlow processing limit

If the NetFlow processing rate exceeds 1,000 flows per probe per second, it may affect OpManager MSP’s performance. It is recommended to keep the NetFlow processing rate within the specified limit.
