Getting Data In

How to use the metadata command to search for hosts that have recently started sending data to Splunk?

Path Finder

I'm trying to use the metadata command to find hosts that have recently started sending logs. Basically when firstTime is more recent than 7 days. This is the search I have...

| metadata type=hosts index=* | eval firstday=strftime(firstTime,"%Y-%m-%d") | where firstday>=relative_time(now(),"-7d")

I have tried many variations of this, to no avail. The 'firstday' field shows accurately, but the results are not filtered. Is there something I don't understand about this metadata command? I appreciate the help!

Calculate the age of the firstTime
Evaluate against 7d value
7 days = 604800 seconds

| metadata type=hosts index=_internal | eval age=now()-firstTime | where age<604800

Actually this gave what appears to be more accurate results. I'll have to see why the other answer isn't giving exactly accurate results. Thanks!

firstTime is epoch
firstday is string
relative_time is epoch

Simply do it this way:

 | metadata type=hosts index=* | where firstTime >= relative_time(now(),"-7d")

Wow, I was afraid it was something simple. This worked perfectly, thanks!!

This looked right, but after trying the answer below the results are different, and it looks like it's producing more accurate results. I'll dig into why.
