(I replace the network equipment name by XXXXXXX.)
I change the timezone in the php.ini file because if I let one of venezuela I'm -4h30 and not -4h.
I was replace date.timezone="America/Caracas" (GMT -4h30) to date.timezone="America/Virgin" (GMT -4) but the problem is always present.

My php.ini

Code: Select all

[Date]
;date.timezone="America/Caracas"
date.timezone="America/Virgin"
; Defines the default timezone used by the date functions
; http://php.net/date.timezone
;date.timezone =

; http://php.net/date.default-latitude
;date.default_latitude = 31.7667

; http://php.net/date.default-longitude
;date.default_longitude = 35.2333

; http://php.net/date.sunrise-zenith
;date.sunrise_zenith = 90.583333

; http://php.net/date.sunset-zenith
;date.sunset_zenith = 90.583333

My php version is : 5.3.17
Cacti version is : 0.8.8a

I was change the timezone in network equipment and on the Windows server that hosts Cacti.

Thanks in advance for your help.

What do your graphs look like? Are they up to date?
Which version of weathermap?
Are you using poller_output in weathermap?

You seem to have jumped straight to a weathermap issue. All weathermap does is ask rrdtool for the last 800 seconds of data ('now-800). No timezone involved.

It's also worth turning on DEBUG logging for one poller cycle, to see more detail about what is happening. Weathermap will log the data it gets from rrdtool.

Hello and thanks for your reply.

Yes the network drawing is up to date, the problem appeared to the time change.

We used weathermap version 0.97a

I'm very sorry but my knowledge in Cacti tool are very limited, how i can check if i used the poller_output in weathermap ?

You can find the Cacti log in attachment.

That's not a complete log, but it looks like you are using poller_output - there would be a line like this near the top of the map file:

Code: Select all

SET rrd_use_poller_output 1

in the map file.

It would be worth trying without that, and see if it helps. Then weathermap is just asking rrdtool for data.

Also grep your complete log for lines with "ReadData" and you can see what data weathermap is getting.
