| description | Use the sum operator in Sumo Logic to calculate the total value of numeric fields within log data, enabling powerful aggregation and analysis. |
sum adds the values of the numerical field being evaluated within the time range analyzed.
sum(<numerical_field>) [as <field>] [by <field>]
- Creates field named
_sum
... | sum(bytes_received) group by hostname
Sample log message:
Aug 2 04:06:08 : host=10.1.1.124: local/ssl2 notice mcpd[3772]: filesize=20454: diskutilization=0.4 : 01070638:5: Pool member 172.31.51.22:0 monitor status down.
Example based on sample log message above:
file*| parse "filesize=*" as filesize
| sum (filesize) group _sourceHost
Finds all messages that contain term file* and parses out all that have a filesize=value. It will then extract the value of filesize and will add all those values per host where those log messages are generated.
When you calculate the sum of more than one field, you must create an alias using the as operator to rename the sum fields. See this example:
_sourceCategory="OS/Windows"
| kv "HandleCount", "ThreadCount"
| sum(HandleCount) as sumHandleCount, sum(ThreadCount) as sumThreadCount
You can use multiple aggregation operators on the same line of a query. For example:
max(amount) as amount_max, count(datetime) as datetime_count, sum(_size) as messages_size_sum, last(query) as last_query
