Understanding telegraf snmp

I’m new to tickstack and snmp and trying to understand the data I’m getting collected into influx related to an snmp request being made through telegraf.

From a shell in ubuntu I run snmpwalk with the following results.
snmpwalk -v2c -ccommunity x.x.x.x
iso. = INTEGER: 0
iso. = INTEGER: 13

Note: if run multiple times the first oid almost always returns 0, the second generally ranges between 8-15.

In my telegraf.conf I have:
interval = “10s”
round_interval = true
metric_buffer_limit = 1000
flush_buffer_when_full = true
collection_jitter = “0s”
flush_interval = “10s”
flush_jitter = “0s”
debug = false
quiet = false
logfile = “installpath/telegraf/telegraf.log”

agents = [“x.x.x.x”]
version = 2
community = “community”
name = “snmp” # This is used for all the fields, of which there are none (yet).
name = “ap_util”
name = “util4”
oid = “.”

In influx I see a row of data every 10 seconds for util4 with either a value of 0 or ranging between 8-15 (the 8-15 range is what I was expecting to see when I first started looking into why we were getting zeros as a outlier).

So questions:

  1. Shouldn’t I be seeing two rows of data in influx? One for each snmpgetnext found during the walk?
  2. It seems like sometimes influx gets the data for the first returned oid in the walk (~25% of the time) and the second oid returned in the walk (the other ~75% of the time). Are both values being written to the same data row in influx and I’m seeing race conditions with one overwriting the other? Some other explanation?
