The following example returns the results of the eval expression eval(method="GET")) AS Views. The following example returns the values for the field total for each day. You can use this function with the timechart command. Returns the values in a field or eval expression for each day. | mstats latest_time(_value) where index=_metrics metric_name=queue.* BY metric_name span=1m It is designed to return the latest UNIX time values in the past 60 minutes for metrics with names that begin with queue. The following search runs against metric data. Alternatively, you can use the rate function counter to do the same thing. If you have metrics data, you can use latest_time function in conjunction with earliest, latest, and earliest_time functions to calculate the rate of increase for a counter. Returns the UNIX time of the chronologically latest-seen occurrence of a given field value.
The search returns the event with the _time value 00:15:05, which is the event with the most recent timestamp. Sourcetype=secure invalid user "sshd" | table _time source _raw | stats latest(_raw) You extend the search using the latest function. You use the table command to see the values in the _time, source, and _raw fields. You run the following search to locate invalid user login attempts against a specific sshd (Secure Shell Daemon). Returns the chronologically latest seen occurrence of a value in a field. | mstats earliest_time(_value) where index=_metrics metric_name=deploy* BY metric_name span=1m It is designed to return the earliest UNIX time values on every minute for each metric_name that begins with deploy. Alternatively you can use the rate counter to do the same thing. If you have metrics data, you can use earliest_time function in conjunction with the earliest, latest, and latest_time functions to calculate the rate of increase for a counter. You can use this function with the mstats, stats, and tstats commands. Returns the UNIX time of the chronologically earliest-seen occurrence of a given field value. The search returns the event with the _time value 00:23:28, which is the event with the oldest timestamp.
Sourcetype=secure invalid user "sshd" | table _time source _raw | stats earliest(_raw) You extend the search using the earliest function.
