Variable snmp data collection with embedded queries

One or more non-transitory more machine-readable media comprising program code for interactive simple network management protocol (SNMP) data collection, the program code to:

• identify among a plurality of metric expressions those that comprise embedded queries for device attributes, the plurality of metric expressions corresponding to a listing of object identifiers;
• after receipt of values from an SNMP data collection based, at least in part, on the listing of object identifiers,
• identify among the values those that are object identifiers corresponding to device attributes of the embedded queries;
• determine SNMP data collection parameters for collecting data from a managed device corresponding to the device attributes;
• for each of the embedded queries,
• resolve the embedded query to an implementation of the embedded query;
• instantiate the implementation of the embedded query with a corresponding one or more of the object identifiers and the SNMP data collection parameters as arguments;
• invoke the instantiated implementation of the embedded query;
• and
• upon receipt of a response to the invoked implementation instance, evaluate a corresponding one of the identified metric expression utilizing a second value from the response.

An apparatus comprising:

• a processor;
• and
• a machine-readable medium comprising program code executable by the processor to cause the apparatus to,
• after receipt of values from a simple network management protocol (SNMP) data collection based, at least in part, on a plurality of object identifiers,
• determine that a first metric expression of a plurality of metric expressions comprises an embedded query for a first device attribute, wherein the plurality of metric expressions relates to the plurality of object identifiers;
• identify from the values a first value collected for the first device attribute, wherein the first value is a first object identifier;
• resolve the embedded query to an implementation of the embedded query;
• instantiate the implementation of the embedded query with the first object identifier and SNMP data collection parameters as arguments according to an argument map;
• invoke the instantiated implementation of the embedded query;
• and
• upon receipt of a response to the invoked implementation instance, evaluate the first metric expression with a second value from the response.
