Cacti

I cant find out how to erase a graph

I didn't get the data on my server for some reason (Redhat 7.3). I had to replace the lynx command with the wget command and after that everything went fine. $output = `/bin/bash -c 'wget --quiet -O - \"http:\/\/localhost\/server-status"'`; $output =~ /Total accesses: (.*) - Total Traffic:...

The error was that cactiuser can not execute "lynx" with the cmd.php.
I don't understand why, I even set the chmod 777 to /usr/bin/lynx.

I ended up replacing lynx with wget in the script.

I loged in as cactiuser, executed cmd.php and everyting went fine. Even the logfile sad it. [cactiuser@mailkast cacti]$ /usr/local/bin/php /var/www/cacti-0.8.5/cmd.php But when I use the crontab only one graph is not updated. */1 * * * * cactiuser /usr/local/bin/php /var/www/cacti-0.8.5/cmd.php How ...

I loged in as cactiuser and run the unix_apachestat.pl script just fine.

But still when I check the log file I get a :
apache_idle_workers N::::

The rrd gets updated, I gues the privilges are right.

I want to see status of apache, mysql remotely.
I thought the only possibility is to use SNMP but how do you
put the value into a MIB?

Thanks

Cacti is running fine right now, but I will start making this changes in about 2 weeks. I hope I can drop questions to you if i got some.

what is catistoric? I actually want to graph real time. We want to protocol the behavier of our sever when the programm is running, which leasts for about 20 seconds. Should I better use a regular monitoring Tool for that purpose?

I tried this on my laptop and it works better: LPME:/var/www/php/cacti# snmpd -v NET-SNMP version: 5.0.7 Web: http://www.net-snmp.org/ Email: net-snmp-coders@lists.sourceforge.net In about 2 weeks I will be at work again and I check what version didn't work there. I guess it s 5.0.8 and its Redhat 9...

cmd.php runs as cacituser. I dont think ist a problem from the intallation

cmd.php

snmp: 127.0.0.1:161, dsname: cpu_system, oid: .1.3.6.1.4.1.2021.11.52.0, value: No Such Object available on this agent at this OID

why is that?

normaly a graph is about 1 day long. when i set the cmd.php to 30seconds
interval, can i get cacti to show me one graph which is 1 hour long?

I just want to graph the performance of my computer (cpu, mysql, sendmail,etc....) when executeing a programm on my server for about 2 minutes.

I always have to change the permission by hand when i created a new data source rrd. Why is that?

Kinda strange is, the rrd files at first belong to root.
when i execute cmd.php it tells me that it updated the rrd file. but didn't

I am trying to graph MySQL, Apache, eth0, with Cacti.
Have been many hours on the internet and found out that they use SNMP to comunicate. Is that True??
If yes how do I find the name,MIB or what I need to create a graph in cacti?

my Linux always looks at the wrong paht for the mysql.sock
I tried to find the configuration file where I can change that, but could find it.

Anyone nows where I can change that?
