SNMP Plugin Help
Gets data from various servers and other network devices via Simple Network Management Protocol (SNMP).
Sensors:
- Get
Parameters:
- Community: The community the OID is contained in. The default is "public" (no quotes).
- ErrorString: When a generic error occurs, what is the string returned (includes timeouts). Default is "Error"
- Host: The host to get the information from.
- NotUpdatedErrorString: When the data isn't update because of a previous error with access to the machine, the string that is returned. Default is "Error: Not Updated".
- OID: The OID of the data to get.
- Retries: The number of retries (see note below).
- ServerRetryTime: The timeout between retrying each server after a failure (in seconds). The default is 30 seconds.
- Timeout: The timeout value for the SNMP service (see note below), in milliseconds.
Notes:
The retries and timeout parameters are for use with the SNMP service, and relates to how long to wait once the request has been sent, and how many times to retry to get a response. This is used when the server itself is up, but the SNMP service is down/busy and it's response time. The network timeout on the other hand, is a separate issue. When the server itself is down, the "ServerRetryTime" parameter, can be set so that if the first call to server fails for some reason, then all of the following queries to the same server for the next n seconds will return an error automatically, rather than having to wait (in the case of a network timeout). To see if this is occuring, the error string is different.
Changelog:
1.0.1.0
* If the value returned should be an number, it returns it as a number now, so that it is useful in the bar plugin for example.
1.0.0.6
* Added some options to stop the checking of machines that are down for a certaing period.
* Added options for error strings.
