Best way to update a monitoring configuration for SNMP extension?

AntonioSousa — Mon, 15 May 2023 08:01:47 GMT

I need to add/remove devices from a certain monitoring configuration for a certain SNMP extension.

Now, an existing monitoring configuration can be read, but when read, it doesn't show the community strings of existing devices. It does show some random number in the middle:

{ "ip": "192.168.1.1", "port": 161, "authentication": { "type": "SNMPv2c", "community": "***346***" } }

Every time I get the data, the numbers change. Does posting this data back to the API mean the community string will be maintained? What care has to be taken, so that Dynatrace doesn't interpret this Community string linearly?

BTW, I'm thinking in using the /extensions/{extensionName}/monitoringConfigurations/{configurationId}
endpoint. Or is there any other better way?

Hi,

community string contains a secret value, so API returns a temporary replacement. To prevent the secret value from being modified, the configuration should be updated with exactly the same temporary value.

@witold_turzansk,

Thanks for your answer! Given that the reply is different, or at least it seems, which limitations for reusing the temporary value apply?

Is it time driven, so that if I submit the update request in a certain amount of time, it will still apply?
Is it request driven, so that after each "GET", I have to do an update following?
Combination of the above?
Other?

The starred value for the secret is valid until the next update, so after first use in an update request it must be read again.
