Hi All below is my Flag file, for some reason I do not receive any event to my tls server. For some reason I am getting
Event publisher not enabled: syslog: Publisher disabled via configuration"
Any idea someone ? Flag File:

About the "Publisher disabled via configuration" message: that is not an error. It is just informing you which publishers are not enabled
2:01 PM
Make sure you have scheduled queries running, then start osquery with --verbose and look at the messages to determine what is going on

We do not have scheduled queries as staging of the events is disabled and send directly to the tls server.
2:13 PM
--disable_events_staging=true
Not as mentioned above That is to avoid to fill up the disk

i don't think that's an osquery flag
2:15 PM
is it a private fork? you probably need to seek support to your vendor
a

Avi Apelbaum

03/19/2020, 2:17 PM
Ow yeah , you’re right 🙈

is it Uptycs? they have people in here

Avi Apelbaum

03/19/2020, 2:18 PM
We used to have uptycs, probably the conf file remaind there . We already installed the native one.

03/19/2020, 2:19 PM
ah I see!
2:19 PM
they are using a really old version of osquery
2:19 PM
the config may have changed quite a lot
a

Avi Apelbaum

03/19/2020, 2:19 PM
Yes they are
2:19 PM
version 3
2:19 PM
3.3.

you can probably use the ephemeral db plugin
a

Avi Apelbaum

03/19/2020, 2:22 PM
What is that, can you elaborate ?
a

alessandrogario

03/19/2020, 2:22 PM
though it's not quite like what i think
--disable_events_staging
was doing
2:22 PM
it is an in-memory db, that gets lost when osquery restarts
a

Nice, will read about it , thanks!
a

has less overhead compared to rocksdb (which attempts to store data in a corruption-resistant format so it persists across restarts)
2:24 PM
but it's not like bypassing the db entirely (which is what I think that flag is doing)
a

Avi Apelbaum

03/19/2020, 2:25 PM
OK thanks for the information.
2:25 PM
Anyway , I do not have anything in those tables.
2:25 PM
I just checked

--audit_persist=false
2:26 PM
is auditd running?
a

Avi Apelbaum

03/19/2020, 2:26 PM
auditdnetlink.cpp:613] Failed to set the netlink owner
a

alessandrogario

03/19/2020, 2:26 PM
that flag is usually enabled
2:26 PM
but will cause errors if there's another audit-based service running

It seems to work, must see how i can prevent from the disk to fill up. WIll check the ephemeral db
