CRITICAL ISSUE Possible Bug - 1.1beta2 upgrade 1.1beta5 -> agentd (supported tests) [Archive]

SAT QPass

25-01-2006, 20:13

Zabbix is running and compiled on the following box
Red Hat Enterprise Linux ES release 3 (Taroon Update 5)

To summarize the issue, 1.1beta2 zabbix_agentd reports some 125 tests that it is capable of. However, when I compiled 1.1beta5 zabbix_agentd on the very same box, zabbix_agentd reported only 20 some tests. This obviously poses a great consternation to me and I am hoping some here could please shed some light on the situation. I have included the output from ./configure -enable-agent (exit status with option information) and the output of zabbix_agentd -p for both 1.1beta2 and 1.1.beta5.
For reference, the box and packages have NOT changed between compiles.

Any help would be greatly appreciated.

Output from 1.1beta2 ./configure --enable-agent is attached.

1.1beta2 ./zabbix_agentd -p (zabbix_unsupported statements removed because of character limit for post):

The report provided by 1.1beta5 agent does not give you all possible conbinations of supported parameters. It just provides basic information. For example, it says that vm.memory.size[total] is supported, however in reality all the following parameters are supported:

vm.memory.size[total]
vm.memory.size[free]
vm.memory.size[cached]
vm.memory.size[used]
vm.memory.size[shared]
vm.memory.size[buffers]

See ZABBIX Manual for complete list of supported parameters by platform. Do not rely on output of zabbix_agentd -p.

If that were in fact true.... Then I am curious as to why the server only received the variables listed from -p. I upgraded from 1.1beta2 to 1.1beta5 via the SQL path and yet, all the previously configured items were all coming back as NOT SUPPORTED via the frontend and zabbix_server.log file.

Do I have to completely dump my database and start from scratch? Why would all the previously defined items fail?

As soon as I restored the 1.1beta2 zabbix_agentd they were all supported again.

Apologies for providing incorrect information. The old naming of items is NOT supported anymore. You have to rename your items. Keeping old naming supported would greately increase agent's internal structure, that's why we decided to drop backward compatibility at some point.

OK,

I'm back in the zabbix game for a while, need to upgrade to beta5 or better.

That being said, Alexei.. could you provide a map of olditem to newitem names so that a sql script can be generated to update older databases?

Or, if you have one already... post it? :D

It would be quite difficult to create such a patch. Some parsing will be required and this cannot be done by SQL.

I believe the mapping is quite straight forward. Look at ZABBIX Manual, it has old naming in description of the new items.

I made a quick item to item map and script to update the items in the database.

I posted it on the wiki in the users contribution section so if anyone wants to use it, update it, or add something I've missed feel free :)
