Configuration of ZABBIX API and PHP

Because the nearest online Hadoop colony from mrv1 Upgrade to mrv2 了 , The monitoring template has also changed ..

Online is 200 Right and left colony , The module uses link To add , Under one template link A large number of modules , Then add the host to this template .

In this way, a machine has almost 215 individual item.

To increase NM Monitoring of , It also uses link To connect templates , On the page link I found that a blank page has been returned .

In order to get online quickly , Changed the method , Used host.update Of api, Put... Directly host link To NM The template of .

Looking back on this question ：

Through the page link Template time , In fact, it is called zabbix template dependent api（ Specifically called template.update Method ）

Call... Directly through a script api test ：

The test script ：

#!/usr/bin/env Python

Script results ：

urllib2.HTTPError: HTTP Error 500: Internal Server Error

because api In fact, it sent a jason Format post request , Manual use curl To verify ：

curl  -vvv -i -X POST -H 'Content-Type:application/json' -d

'{"params": {"templates": [{"templateid": "10117"}, {"templateid": "10132"}, {"templateid": "10133"}, {"templateid": "10134"},

return 500 error （ Back end php Errors encountered during processing result in ）, adjustment php Configuration of , Change the log to debug Format ：

php-fpm.conf:

log_level = debug

stay error log The following errors were found in ：

I'm doing it link Template time , You need to put the relevant data in php The memory of the , The default setting is 128M, If in item and host More often , It's easy to exceed that limit .

Change to

memory_limit = 1280M

To test , Back to 502 Bad Gateway error , That is, the back-end execution timeout leads to .

error log:

[04-May-2014 14:50:21.318071] WARNING: pid 4131, fpm_request_check_timed_out(), line 281: [pool www] child 4147, script '/apps/svr/zabbix/wwwroot/api_jsonrpc.php' (request: "POST /api_jsonrpc.php") execution timed out (10.030883 sec), terminating

Execution time exceeded request_terminate_timeout Set up . Lead to 502 produce .

change request_terminate_timeout = 1800（ The default is 10s）,max_execution_time = 0( Default 30s), To test .ok.

Summary ：

zabbix Different from general online applications , Calling api When updating , It's a batch act , There are certain requirements for memory and execution time .

So set it reasonably php Related parameters of , stay debug Lower the log level and turn it on slow log To facilitate positioning problems .
