Ping polling properties and metrics
For chassis and interface ping polls, you can specify ping properties such as timeout periods and number of ping retries. You can also collect ping metrics, such as response time and packet loss.
You can specify the following ping properties when creating a chassis
or interface ping poll.
- Timeout
- Specify, in milliseconds, how long the polling process should wait for a response from the target device before sending a new ping packet.
- Retries
- Specify how many times the polling process should attempt to ping the target device before giving up. When Packet Loss metric collection is enabled, the polling process sends this number of ping packets regardless of whether a response is received.
- Payload size
- Select the size of the ICMP packet to be used for the ping request. Select the default (32 bytes) or choose a custom size. This setting overrides the value of IcmpData in the NcPollerSchema.cfg configuration file.
CAUTION: Using a size smaller than 32 bytes may result in packets being dropped.
You can collect the following ping metrics when creating a chassis
or interface ping poll.
- Response time
- You can opt to collect data on the round trip time for ping tests. This is measured in milliseconds. When Packet Loss is also being collected, this is the average response time for each successful test.
- Packet loss
- You can opt to collect data on the number of ping packets for which the polling process did not receive a response. This is stored as a percentage.
