How to convert seconds to days?

This search:

index=perfstats host=hostname | chart max(System_Up_Time) as "System Uptime" by host

Outputs a value such as this:

85486.676230500001

Just trying to convert this value in seconds to days.

Thanks. Looked at different posts, but can't seem to convert it effectively.

All that you need is an eval command to do the math and store in a new field

index=perfstats host=hostname | eval Uptime_Days = System_Up_Time/86400 | chart max(Uptime_Days) as "System Uptime" by host

The tostring() takes seconds, you've fed it with days. Pick only one way of conversion, not both at once.

Tried to ensure I'm not using multiple conversions at once by using these two searches:

index=perfstats host=hostname | eval Uptime_Days = System_Up_Time | chart max(Uptime_Days) as "System Uptime" by host | eval System Uptime = tostring('System Uptime', "duration")

index=perfstats host=hostname | chart max(Uptime_Days) as "System Uptime" by host | eval System Uptime = tostring('System Uptime', "duration")

No data found on both. Just an FYI, no need to reply if you don't want. The initial reply is good.

Another neat thing is this after the chart:

... | eval System Uptime = tostring('System Uptime', "duration")

That will provide a readable string with days, hours, minutes, ...

you mean like this?

index=perfstats host=hostname | eval Uptime_Days = System_Up_Time/86400 | chart max(Uptime_Days) as "System Uptime" by host | eval System Uptime = tostring('System Uptime', "duration")

I get data like this

00:00:17.723748506149999

Any idea on how to use round function after 17.723748506149999  like 17.72 
when I use round function values no results found.

Firstly, a golden shovel award 😉 you dug up a thread from 8 years ago 😄

But seriously. If you have a field which looks like a number but doesn't work like a number (nummerical functions don't give you expected results), you're probably dealing with a text field containing string representation of a number. You have to convert it to number first.

Try like this

| eval System Uptime = tostring(round('System Uptime',2), "duration")
