Cacti on a Redhat 8 system. What did I do wrong?

[evert]

Hi!

I've installed Cacti, followed the install instructions, and created the graphs for the localhost. It's nicely creating graphs, but they're all empty!

Since I'm kinda new to Cacti: What more info do you need to help me with this problem?

Since I don't know which cacti version do you use and what exactly the problem is I can only guess that it's because of SNMP problem. RH 8.0 had broken (fixed in RH 9) SNMP and PHP integration module (php-snmp rpm package). If this is the case you can do several things: stop using internal php snmp support (in "include/config.php" file find "$config["php_snmp_support"]" variable and set it to false), compile php and net-snmp by yourself or upgrade to RH 9.

I'm using the most recent version: 0.8.4

and it's not (just) snmp: ALL graphs are empty, also the diskfree & loadavg ones...

check out http://www2.telio.no/cacti/ (guest/guest) for what I get so far...

I had a similar problem.

Are you sure that the cronjob for cmd.php is being executed correctly? That piece of code is responsible for filling the databases with data.

I just checked (with a 'touch' in the cron), and the cron runs when it should.

If I run the cmd.php manually, it does generate output, with correct numbers.

What's the line in cron (exactly) and did you try it as root or the user its supposed to run under in cron ?

I have 2 instance's running on RH8 and I seem to remember dropping the "cactiuser" bit of the cron line. (so cmd.php) runs as root effectvely. It maybe of course that I screwed my permissions up somwhere though.

I found it!

Somehow the perms. on rra/ & log/ had not been set to chown cactiuser or reverted back to root.

Now it's working!


Thanks for the help, everyone!
