[SOLVED]date problem

[luffywallis]

Hi,
I have a cacti installed with "eyesofnetwork". at first, the cacti plotted the graphs, but i saw that the date and time weren't the good ones, so i changed them on the machine using the commands date and hwclock --systohc
after doing that, the graphs are no longer plotted (blank graphs). how can i fix that? thanks!

rrd files are date sensitive. You will have to wait until the 'current' time matches the next open spot in the rrd file before it will start graphing again.

Thanks for your reply.
the old date was 11/11/2011.. is there another way to do it? if i recreate all the graphs will it solve the problem?

[Linegod]

Best bet is to recreate all of the graphs.

You could export all of the rrd files, and manually update every date stamp, but that might be madness...

Well, i deleted all the graphs and created them but nothing happened. So i deleted the devices and created them again (and created their graphs again) but the problem was not solved. Worse, now the devices have an "unknown" status
i took a look when i deleted the devices, and i saw that the directory /srv/eyesofnetwork/cacti-0.8.7e/rra/ is full of .rra files of the deleted devices, so i deleted all of those files (i made a backup in case), but nothing happened..what can i do to fix this?

How long did you wait? Did you check your log for messages?

i waited like 15 minutes

here the last entries on my cacti.log

Code: Select all

you can see that all the entries have the wrong time, so when i changed the time the poller didn't work...



EDIT: i run php -q /srv/eyesofnetwork/cacti-0.8.7e/cmd.php manually on the machine and the devices became "up"
the poller doesn't create .rrd files, even if i run it manually..strange

Now i have this in my cacti.log:

Code: Select all

05/20/2011 08:02:36 AM - POLLER: Poller[0] NOTE: Cron is configured to run too often! The Poller Interval is '300' seconds, with a minimum Cron period of '300' seconds, but only -15299545 seconds have passed since the poller last ran. 

-15299545 seconds brings us to the previous date (~ 11/11/2011) so there is something that still use the "wrong" time and needs to be adjusted..

[luffywallis]

ok now i was able to find a solution to the cron issue, just by modifying poller.php, in the line $force=FALSE turn it to TRUE, run the poller manually and then turn it back to FALSE.
after that, another problem appeared:

Code: Select all

05/20/2011 09:55:01 AM - POLLER: Poller[0] WARNING: Poller Output Table not Empty. Issues Found: 59, Data Sources: traffic_in(DS[155]), traffic_out(DS[155]), traffic_in(DS[156]), traffic_out(DS[156]), discards_in(DS[157]), discards_out(DS[157]), errors_in(DS[157]), errors_out(DS[157]), discards_in(DS[158]), discards_out(DS[158]), errors_in(DS[158]), errors_out(DS[158]), traffic_in(DS[159]), traffic_out(DS[159]), traffic_in(DS[160]), traffic_out(DS[160]), traffic_in(DS[161]), traffic_out(DS[161]), traffic_in(DS[162]), traffic_out(DS[162]), traffic_in(DS[163]), Additional Issues Remain. Only showing first 20 

now i see the graphs but they are empty..still searching for a solution..

resolved! i removed and re create the devices again, and after that it worked!
