Cacti and Nagios Some summary of "seven"

When we install or use cacti, we will encounter a lot of problems, that here reprint a very good article, for everyone to reference and study, thank you very much original!

I. Database-Related FAQs

1. Occurs when PHP is installed or cactid/spine/cacti

Checking for Mysql_init in-lmysqlclient_r ... no

Configure:error:MySQL Libraries not found

Workaround: The PHP Development API could not be managed becausePHP was compiled without adding – with-mysql=/usr/local/mysql

2. Not defined mysql_connect () when making PHP connection database

Workaround: PHP does not have a PHP API associated with it to check if PHP wasadded at compile time – with-mysql=/usr/local/mysql

3. During installation, added – with-mysql=/usr/local/mysql

Appears: Whith "Configure:error:MySQL Libraries not Found"

WORKAROUND: To determine if MySQL can run normally, do not use the binary installation method, self-compilation, problem solving,

Online so-called awards– with-mysql to– with-mysql-dir This is the error, it compiles through because, this configuration is wrong,./configure ignored it.

Two. Other errors

Error One:

11/15/2010 07:34:42 pm–spine: poller[0] fatal:unable to read configuration file! (Spine Init)

11/15/2010 07:44:43 pm–spine: poller[0] fatal:mysql Error: ' 1146′, Message: ' Table ' cacti.settings ' doesn ' t exis T ' (Spine init)

Solve:

Check your spine configuration file, or reinstall spine

Error Two: Error while editing spine

Checking if UCD-SNMP needs crypto support ... no

Checking if NET-SNMP needs crypto support ... yes

Checking for snmp_timeout in-lnetsnmp ... no

Cannot find NET-SNMP libraries (SNMP) ... checking ucd-snmp

Checking for snmp_timeout in-lsnmp ... no

Configure:error:Cannot Find UCD-SNMP libraries (SNMP)

Solve:

Configure when added –with-snmp=/usr/local/net-snmp/your NET-SNMP path

Or do not add or add this parameter– with-static=/usr/local/lib

./configure–with-static=/usr/local/lib

Error Three:

/usr/local/spine/spine

Spine:version 0.8.7b Starting

11/15/2010 05:19:46 pm–spine: poller[0] error:snmp Library Version mismatch (5.3.1 vs 5.3.2.2) (SPINE parent)

11/15/2010 05:00:01 pm–spine: poller[0] error:snmp Library Version mismatch (5.3.1 vs 5.3.2.2) (SPINE parent)

There is a problem with this version of spine and NET-SNMP

Solution :

First uninstall the previously installed NET-SNMTP and spine

Install NET-SNMP and then compile the installation spine at this point you can specify your NET-SNMP can also not be specified, can be.

Error Four

11/15/2010 05:00:01 pm– poller: poller[0] WARNING: Cron is out C6>of sync with the poller interval!  the Poller Interval is ' 60′seconds, with a maximum of a ' 300′second Cron, but Secon DS has passed since the last poll!

11/15/2010 04:56:00 pm–system stats:time:59.2263 method:spine processes:1 threads:1 Hosts:2 HostsPerProcess:2 DATASOURC Es:21 rrdsprocessed:0

11/15/2010 04:56:00 pm– poller: poller[0] Maximum runtime of seconds exceeded. Exiting.

Solve:

Because the cron time is related to the time difference between pollerand PHP.

General Poller. php with a new time of 60s, so cron inside also set to every minute with a new

Such as:

*/1 * * * */usr/bin/php/var/www/html/cacti/poller. php >/dev/null 2>&1

Error Five

Solve:

Temporary.

Delete from settings where name = ' syslog_last_incoming ';

Error Six:

What is the reason why SNMP error sometimes occurs when we add a device?

WORKAROUND: First guarantee both sides SNMP version consistent

2nd, the snmpd.conf configuration file allows the IP network segment to be crawled!
