Definition

Default

Interval

120 seconds

Number of retries

Number of attempts in each monitoring interval before the interval's sample is discarded

3

Number of samples

Number of consecutive samples before the monitor changes state

3

Timeout

Amount of time in milliseconds to wait for a response from the device before the sample times out and a new attempt is made to sample the value

1,000 milliseconds

Causes

A warning state for this monitor indicates that the target IP is not responding to ICMP ping messages.

Resolutions

Ensure that the firewall is configured to allow SNMP traffic. Use the Health Explorer to check the details for the state change on the State Change Events tab for the monitor. This data shows the Object Identifier (OID) and the value that the device returned in response to the query. Consult the device manufacturer's documentation for the device's specific OID for more information on the problem and troubleshooting procedures.
