Getting Data In

Why is my metadata search not returning expected results for hosts reporting in within certain time ranges?

Hi all,

I have written below metadata search to find the hosts which have reported yesterday, but not reporting in the last 1 hour.

| metadata type=hosts |eval current=now() |eval lastHour=relative_time(current,"-1h")  | eval yesterday=relative_time(now(), "-1d") | where ( recentTime>yesterday AND recentTime<lastHour) | convert ctime(current) as Current_Time, ctime(lastHour) as Last_Hour, ctime(recentTime) as Recent | table Current_Time,Last_Hour,Recent, host

This search is returning a list of hosts, but after I dig into these hosts, they seems to be reporting to their respective indexes which means the metadata search is giving me wrong results.

I start breaking up the search and excluded the recentTime&lt;lastHour from the where clause. Below is the resulting search:

| metadata type=hosts | eval current=now() |eval lastHour=relative_time(current,"-1h") | eval yesterday=relative_time(now(), "-1d") | where recentTime>yesterday  | convert ctime(current) as Current_Time, ctime(lastHour) as Last_Hour, ctime(recentTime) as Recent | table Current_Time,Last_Hour,Recent, host

This gives me a list of only 2 hosts, whereas in my environment, hundreds of hosts are reporting.

Not really sure what is happening.

Please help !!

try this for specific indexes.

| metadata index=foo  index=bar  index=baz type=hosts

You want your search to start with:

| metadata index=* type=hosts

I have huge number of indexes so i think i cannot use the metadata command. Could you let me the other approach about going after license logs to get this information.

How do you expect this to work? The metadatacommand reads the metadata stored inside the indexes...

If you only have a handfull of indexes you want to check, you can try this:

| metadata (index=foo OR index=bar OR index=baz) type=hosts

The other approach to base it on your license logs.

This is incorrect:

| metadata (index=foo OR index=bar OR index=baz) type=hosts

For some reason, metadata seems to dislike OR. You can use:

| metadata index=this index=that

It works fine. It does mean that I'm unable to use macros that contain multiple indexes separated by OR with metadata.
