Cacti 0.8.6e cactid cannot create new .rrd, cmd.php does

[irfandp]

I still working on this cacti 0.8.6c that suddenly cannot update rrd and showing 'Nan' and all graph i've been created, it's wierd.

Usually using CMD.php with default setup, but lately this server (FreeBSD 5.2.1 with Sun UltraSparc 2XCPU 450 Mhz Enterprise 220 256M memory) using Swap to much and slowing down entire system.

Then i try to compile cactid 0.8.6e, found some errors in compiling with code RLIMIT_AS in resource.h...but after collecting some useful information from this board, compiling is success.

Give it a try to update .rrd from cacti 0.8.6c...and nothing happens...still no update, but this polling is magnificent ! so fast..... (from avg 400 ms to 10 ms avg..... amazing!). OK then i tried to run CMD.php from shell console with ROOT id, polling when well and updating the .rrd and from cacti.log, cactid UPDATING the .rrd too !!!!

I try upgrade to cacti 0.8.6e engine, an try to create fresh new monitoring to snmp enabled cisco router.... result no good, after monitoring DEBUG log for quite sometimes, still no .rrd created for that new device. Well, i try shell console CMD.php again with ROOT id, and slowly in the end of STDOUT, it CREATING the .rrd of new device !!!

then, i looked to cacti.log for cactid polling, and it UPDATING the new .rrd with new data...!!! and graph showing well....

How strange !

Now, I change the crontab ID to running poller.php with id ROOT, and still cannot create new .rrd for new device.

Is it the problem with chown and chmod on the filesystem ? or is it some bug on cacti database ?

Well, if i have to CMD.php shell after creating 100 new devices, it would be wasting my time .

Any Idea with this issue ?

Please edit your <sys/resource.h> file and add the following:

#define RLIMIT_AS 6 /* address space (virt. memory) limit */

Then, remake cactid. After that, please open a bug report with your *nix vendor.

As far as your other issues, I would need some more information. Please run "php -m" post output. What version of net-snmp are you using? Do you have any abarent Data Sources (goto Data Sources, select Host "None") in your database?

Hereis my config :

Code: Select all

> php -m
[PHP Modules]
ctype
mysql
overload
pcre
posix
session
standard
tokenizer
xml
Zend Modules

And i'm using net-snmp-5.1 and rrdtool-1.0.45 from FreeBSD packages.

And No data source available on that directive, just blank.

Today, I will try to create new device leaving CACTID to create the .rrd's hopefully working.

strange thing happen again...after successfully create new .rra's with CMD.php and updating the data with CACTID for about 5 minutes graphs, anda then it won't graph ANY data at all from the new .rra's !!?...

seems like CACTID not updating anything again on those .rra's ..

well, I hate to go back to CMD.php .. it swoop my system into slow motion... otherwise i should remove entire monitoring system to the new server that we cannot afford in short time while.

please run cactid.exe from the command line from the cactid directory. Run it in DEBUG mode. Post your results.

I changed the monitoring method in "Setting" > "Poller" ... last time i use SNMP and Ping to monitor..... ( chown on CACTID binary was "cacti:wheel")... so many device DOWN but graph still available for old device / .rra's ...

After i change Setting > Poller to SNMP only and i change chown on CACTID binary to root:wheel ... Almost all device UP ..... and I try to create new device ... it created ..... .rra's created and updated regulary with CACTID ... graph showed up nicely ...

CRONTAB for POLLER.PHP still activate on user ROOT now ... not in CACTI-user mode ....

strange ? it should be run normally in cacti-user, isn't it ?

You should not have to run as root. However, you must insure that the permissions for the account you are using are correct. You must have rw to both the <cacti>/log and <cacti>/rra directories as well as r to <cacti> and it's subdirectories.

All permissions and chmod status on cacti directory is set to cacti-user ...

cactid binary directory and its binary still on root user ..

[TheWitness]

You poller can run as root. However, your web server should never run that way...
