Unable to view graphs after cacti installation.

[nishith]

Configured "cacti 0.8.7e" on my "CentOS 5.2" version.

After successful installation, i am unable to see "localhost" graphs in cacti.

httpd.log is saying below listed message.

tail -f /var/log/httpd/error_log
ERROR: opening '/var/www/html/cacti/rra/localhost_load_1min_5.rrd': No such file or directory
ERROR: opening '/var/www/html/cacti/rra/localhost_hdd_free_8.rrd': No such file or directory

By visiting cacti forum, i have downloaded "hostinf.tar.gz" & extracted it in "/var/www/html/cacti" which is the default DocumentRoot for "cacti"

what should i do now?

Waiting.

Read the documentation...

You need to setup the poller in cron.

Dear Friend,

Crontab has already modified. Below is the entry in crontab.

*/5 * * * * cactiuser php /var/www/html/cacti/poller.php > /dev/null 2>&1

What else i need to check?

[nishith]

I am getting below notification in my cacti.log file,which is located at
"/var/www/html/cacti/log/cacti.log"

Also let me know which file should i check to get the solution for cacti?

I have installed NAGIOS on the same CentOS Linux Server & I would like to combine "Nagios & Cacti" for better output of graphs & monitoring logs.

Is there any particular documentation available to merge "Nagios & Cacti" & I can monitor my servers & network Devices?

I have AIX 5.1.2 Servers,having Oracle Service configured. Now,i want to monitor all 3 AIX Servers without anabling SNMP in AIX OS.

Is it possible through cacti? If Yes, How many services can i monitor by using cacti?

Below is my crontab entry.

*/5 * * * * cactiuser /usr/bin/php /var/www/html/cacti/poller.php > /dev/null 2>&1
*/5 * * * * cactiuser /usr/bin/php /var/www/html/cacti/cmd.php > /dev/null 2>&1

Below is the output of "/var/www/html/cacti/log/cacti.log"

I am getting data,but graphs are still not visible.

Please help me out. I have followed all the installation instructions given on the website.

"/var/www/html/cacti/rra directorty & /log direcotry is having"cactiuser" permission.

What else i need to check?

Dear All,

Now,i can generate graphs. What i did is given below.

1) Don't forget to install "spine" after cacti installation.

2) Make sure you have configured "poller" entry in crontab as suggested by "cacti documentation"

3) you can modify crontab entry either as a "root" user OR "cactiuser"

In my case,i modify crontab for 5 mintue poller period,which didn't work.

4) Make sure your crontab service is running.
service crontab status/start/stop/restart
chkconfig crontab on ( for startup )

5) Don't modify "poller" entry from 5 minutes to 1 minute. If you Do, you need to
modify many more things,which will become headache.

6) Use both entries "poller.php & cmd.php" in crontab.

Thanks,

1) Don't forget to install "spine" after cacti installation.

This is definitively an optional step. But for optimum performance, it is required

2) Make sure you have configured "poller" entry in crontab as suggested by "cacti documentation"

3) you can modify crontab entry either as a "root" user OR "cactiuser"

In my case,i modify crontab for 5 mintue poller period,which didn't work.

If you run the system-wide crontab of /etc/crontab, you will have to specify the userd. If you run the crontab of cactiuser, the userid must NOT be specified. That's how cronatbs work.

4) Make sure your crontab service is running.
service crontab status/start/stop/restart
chkconfig crontab on ( for startup )

A good hint. Will use this for the documentation site.

5) Don't modify "poller" entry from 5 minutes to 1 minute. If you Do, you need to
modify many more things,which will become headache.

This is correct!

6) Use both entries "poller.php & cmd.php" in crontab.

I fear that this is not correct. Please post crontab entries to judge

Problem solved. As per the documentation,Now graphs are working on Linux localhost.

Also,i would like to know about to generate graphs of my Network devices thru. SNMP.

Kindly provide me some good documentation for the same.



Thanks,
