Cannot tell that logs are being loaded #6

Closed GoogleCodeExporter closed 8 years ago

GoogleCodeExporter commented 8 years ago
I have loaded a node and a web using the install.sh script and when I tail 
/var/log/elsa/node.log I get what looks like proper activity as far as I can 
tell.  I am attaching an excerpt from node.log so you can see if I am missing 
something.

There are definitely lots of logs arriving on the system as verified by tcpdump.

Yes, no matter what query I do I always get an empty result set even using an 
IP that I have seen with tcpdump as having arrived from evtsys on a windows 
server.  I have other firewall logs which the system does not know how to parse 
which I expect at this time to be missing.

Also, the stats pages shows no information on the graphs for stats: load, 
stats: index and stats: archive.

Something seems to be awry but I am not sure how to best troubleshoot.

Can you please help me sort this out?

Also, I am attaching an excerpt from web.log for the last query I tried to run 
with "10.139.0.2" as the query.  I tried to manually run all of the queries 
from the log and they all returned 0 rows.

Ok, according to the log files, no logs are making it into ELSA.  Since you've 
verified logs are arriving at the system, it's possible that syslog-ng isn't 
piping them to ELSA for some reason.  One cause may be that the OS's syslog is 
already running and listening, which is blocking syslog-ng.  A way to check is 
to look at the syslog-ng log file in /data/elsa/log directory and verify that 
the destination "d_elsa" has logs processed.

Hmmm.  Good point.  I have reconfigured syslog-ng for ELSA to use port 5140 and 
reconfigured the log forwarder to send logs to port 5140.  I can verify on the 
sending side logs are being sent and on the receiving side (ELSA) that logs are 
being received on port 5140.  Still the node.log shows as it did before.  

Not sure how to check the syslog-ng log file since d_elsa writes to elsa.pl.  
Maybe a debug somewhere in elsa.pl to check traffic flow?

What do you see if you do lsof -p 23825?  Is syslog-ng indeed listening on 
5140?  What does your syslog-ng.conf file look like?

Original comment by mchol...@gmail.com on 10 Feb 2012 at 9:09

GoogleCodeExporter commented 8 years ago
I have restarted syslog-ng since then so the PID has changed but here are the 
equivalent results.

Yes, syslog-ng is listening on 5140:
tcp        0      0 *:5140                      *:*                         
LISTEN

And at the end of the LSOF output:
syslog-ng 11024 root    6u  IPv4           42637693              TCP *:5140 
(LISTEN)
syslog-ng 11024 root    7u  IPv4           42637694              UDP *:5140

If I add a new destination to the syslog-ng file as follows I get syslogs into 
the file.  But, nothing seems to be making it to elsa.pl.

destination d_file { file("/var/log/syslog-test.log"); };

log {
...
destination(d_file);
};

Found an article mentioning syslog-ng-ctl as a potential utility for debug and 
it does help.  Shows that logs are being processed:

Ok, elsa.pl is definitely the problem, then.  Try this:
echo "test" | perl elsa.pl
Are there any error messages?

Here is what I get with that command:

Ok, run update-from-svn.sh to grab the latest code which has a small fix in it 
to remove the "sql_error" problem.  However, you will still get a "column 
'start' cannot be null" error.  In the /data/elsa/log/node.log file, what is 
given for "args:" just above this error?

Still a no-go on live data feed.  I tried a sample log entry that I forwarded 
in ticket 5 and still the same output as commend 13 above and no data showing 
in the database.
I do not know if this is the way it is supposed to be but there are no tables 
in the database syslog_data.  Not sure how that one is used but from the 
comments it looks like that is where the actual data for the logs is stored.  
If that is the case, there should be tables and the fact that they are missing 
is a bad indicator.  Is that maybe the reason for no log loading?

There is an error during the create_table routine in which the tables
that actually store the data are created, which is why you're not
getting any data.  Run the update-from-svn.sh one more time and try
the echo "asdf" | elsa.pl again.  I think there may be a difference in
the way your version of either Perl or MySQL handles undefined values
at insert time.  The new code will have Perl set at time if none
given.

Ok, now at version 184.  I have perl 5.14.2 on CentOS 5.6.

This time I get :

What do you get when you run the MySQL query:
SELECT * FROM syslog_data.syslogs_index_1 LIMIT 10;

Do you see any logs saying "Processed n records" where n is greater than 0?
