Performance problem with syslog plugin

Post by randypunter »

Hi There,

I have recently setup a new cacti server, using the prebuilt packages,

I have setup the syslog plugin, and configured rsyslog to accept messages from my network, everything is working ok, but the performance of the syslog.php script is appalling, sometimes taking many minutes to display the messages.

My rsyslog.conf is here

$ModLoad imudp
$UDPServerRun 514
$ModLoad ommysql

$template cacti_syslog,"INSERT INTO syslog_incoming(facility_id, priority_id, program, date, time, host, message) \
values (%syslogfacility%, %syslogpriority%, '%programname%', '%timereported:::date-mysql%', '%timereported:::date-mysql%', '%HOSTNAME%', TRIM('%msg%'))", SQL

*.* >localhost,syslog,cacti,xxxx;cacti_syslog


my config.php is here

$use_cacti_db = false;

if (!$use_cacti_db) {
$syslogdb_type = 'mysql';
$syslogdb_default = 'syslog';
$syslogdb_hostname = 'localhost';
$syslogdb_username = 'cacti';
$syslogdb_password = 'xxxx';
$syslogdb_port = 3306;
}else{
$syslogdb_type = 'mysql';
$syslogdb_default = 'syslog';
$syslogdb_hostname = 'localhost';
$syslogdb_username = 'cacti';
$syslogdb_password = 'xxxx';
$syslogdb_port = 3306;
}

/* field in the incomming table */
$syslog_incoming_config['dateField'] = 'date';
$syslog_incoming_config['timeField'] = 'time';
$syslog_incoming_config['priorityField'] = 'priority_id';
$syslog_incoming_config['facilityField'] = 'facility_id';
$syslog_incoming_config['hostField'] = 'host_id';
$syslog_incoming_config['textField'] = 'message';
$syslog_incoming_config['id'] = 'seq';


if I run php /usr/share/cacti/plugins/syslog/syslog_process.php --debug

SYSLOG: Syslog Table is NOT Partitioned
SYSLOG: Deleted 0, Syslog Message(s) (older than 2017-03-27)
SYSLOG: Unique ID = 14
SYSLOG: Found 49, New Message(s) to process

SYSLOG: Deleted 0, Syslog Statistics Record(s)

2017-04-26 20:59:38 - SYSTEM SYSLOG STATS:Time:0.15 Deletes:0 Incoming:49 Removes:6 XFers:0 Alerts:0 Alarms:0 Reports:0


However the performance is still taking over 2 minutes to load any pages in the syslog tab.

Please help

How many devices? How many rows in syslog table?

Maybe it's better to used a partitioned table? You should move that table to InnoDB and look at the recommendations in Cacti's installer too.
