![]() reltimeĬreates a field named "output" which displays stuff like "Last event was 27 seconds ago." And you don't have to do the math yourself. (If I understand what you want.) yoursearchhere The time returned by the now () function is represented in UNIX time, or in seconds since Epoch time. Usage The now () function is often used with other data and time functions. | eval freshness = now() - _timeĬalculates "freshness" as the number of seconds between the event timestamp and the time that the search started.įinally, you might also try the reltime command for what you want. And one more question gcusello before I let you go. Date and time format variables Time modifiers now () Description This function takes no arguments and returns the time that the search was started. So what you see may well be different from the value that is actually stored, but it will be consistent. This function takes three arguments: a UNIX time X, a time-format Y, and a timezone Z, and returns X using the format specified by Y in timezone Z. So if you had your user timezone set to Pacific Time, then the Splunk UI will display all times (including _time and now()) in Pacific Time. strftime(time, format, timezone) This function formats a UNIX timestamp into a human-readable timestamp. That said - when you sign onto Splunk, there is a time zone associated with your user account. If Splunk has read your timestamp (without the year) and parsed and indexed it correctly (you can compare the the timestamps in the events with the timestamp next to the blue down-arrow-thingy to the left of the event), then you can skip the first part and use the time field, which is already in epoch. strftime() : It is an eval function which is used to format a timestamps value Let’s say you have a timestamps field whose value is like : 1. UPDATE: Ah, ziegfried has an important point. Click the links below to see the other blog. This blog post is part 3 of 4 in a series on Splunk Assist. strptime() : It is an eval function which is used to parse a timestamps value 2. So my question is, how to get the duration and with the format Hours:Minutes:Seconds. You can find more info here: How timestamp assignment works function which are used with eval command in SPLUNK : 1. Perhaps the time zone information is not being picked up somewhere along the way, or nf needs to have a timezone setting on the indexer. If the data does not have the proper time, it may be because the Splunk admin who set up the forwarding missed something. So, the data is always stored in the index with _time in UTC. When the data comes from a forwarder, the forwarder (version 6.x) supplies local time zone information that Splunk uses to calculate _time in UTC. There are variables that produce dates, variables that produce times, and variables that produce both dates and times. As arguments to the relativetime () and now () evaluation functions. I think you have most of this from the other answers, but let me summarize: To define date and time formats using the strftime () and strptime () evaluation functions.
