Graphs not updating

[Thib]

Hey,

I have some problems with my zabbix,

I've done a dump of my database, in order to move the BIIIIG ibdata file created by zabbix.
So, what i did,

1°) mysqldump on zabbix database
2°) mv ibdata1 anotherplace
3°) mysql > remove database zabbix;
4°) mysql > create database zabbix;
5°) mysql > import of the dump created on the new zabbix database.

Now, i have some troubles with graphs : last values are OK, but not graphs.

All i can see in my zabbix_agent log is
6315:20100707:115456.018 Can't parse list of active checks. Can't open JSON object "NOT OK"
6315:20100707:115656.027 Can't parse list of active checks. Can't open JSON object "NOT OK"
6315:20100707:115856.076 Can't parse list of active checks. Can't open JSON object "NOT OK"
6315:20100707:120056.086 Can't parse list of active checks. Can't open JSON object "NOT OK"
6315:20100707:120256.103 Can't parse list of active checks. Can't open JSON object "NOT OK"

so, what can i do?

1. you should have created the new database with utf8 charset;
2. is zabbix server running ?

[Thib]

Yes it is, i've also tried to reboot it, then can see on my map the "Zabbix Server is unrecheable", which is correct.

Do i have to erase again my database, in order to create a new one specifying the charset ? (how do you charset a nee database when creating it in commande line?)

[richlv]

you can either delete the db and create new one according to installation instructions (http://www.zabbix.com/documentation/...#zabbix_server), or you can convert it - see portion of upgrades/dbpatches/1.8/mysql/upgrade script

edit : oh, but your problem most likely isn't caused by that. check zabbix server logfile - any errors in there ?

[Thib]

mmmh ok, i dont understand.

i can choose my own period of view, you know, 1h, 2,, 4h, 1week, etc
when i set it on "week", that gives me the screen i gave you. And i'm told the last value is 931GB what's wrong
when i set in on "2h", the values are ok, the graph is OK, and my last value is correct...

..? o_O

[richlv]

hmm. i somehow missed it on the first run... but that's zabbix 1.6. so it's a bit... old.
is it at least latest 1.6 version ?

[Thib]

Nope it's not, it's an 1.4 version

You can understand why i'm updating

Anyway, thank you four your answers

[richlv]

oh. then i suppose there's not much use trying to figure out why there are some oddities
