Why do we need to use both partialSNMP and multipleGetBulk options together?

Hi All,

I have some questions regarding the use of partialSNMP and multipleGetBulk options in SNMP table polling.

According to the documentation:

  • The partialSNMP option is described as: "When polling large SNMP tables, you can use the partialSNMP:x option to fetch only 'x' rows at a time."

  • The multipleGetBulk option is described as: "Gets the table contents, retrieving multiple rows at once."

I've seen configurations using instance;partialSNMP:X;multipleGetBulk:X, and I'm wondering why both options are needed, as they seem to perform similar functions.

Thanks!

Hi Jason,

I believe multipleGetBulk is focused more on performance; as in how many rows are fetched per GetBulk request.

partialSNMP's focus is on reliability; as in even if one GetBulk fails or returns incomplete data, you tell it to keep going on - this way you might get some data instead of none.
