sum Grouping Operator
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(bytes_received) group by hostname
Sample log message:
Aug 2 04:06:08 : host=10.1.1.124: local/ssl2 notice mcpd: 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
filesize=value. It will then extract the value of filesize
and will add all those values per host where those log messages are
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:
| 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
