Zabbix optimization 2: Active agentd Mode

When the number of hosts is too large and the server collects data, zabbix has serious performance problems, mainly as follows:

1. Web operations are very slow and may cause 502 errors.

2. layer break

3. Too many processes (POLLAR) are enabled. Even if the number of items is reduced, adding a certain number of machines will also cause problems.

Therefore, we will consider the following two optimization aspects:

1. Use proxy or node mode for distributed monitoring

2. Adjust agentd to Active Mode

Because the first solution requires adding physical machines, try the second solution first.

I. Configuration Adjustment of agentd:

LogFile=/tmp/zabbix_agentd.logServer=14.18.xxx.xxxServerActive=14.18.xxx.xxHostname=119.146.xxx.xxRefreshActiveChecks=60BufferSize=10000MaxLinesPerSecond=200Timeout=30

The important parameters are serveractive and hostname. serveractive specifies where the data collected by agentd is sent. hostname must correspond to the host name when the server is added, in this way, the server receives the data to find the corresponding relationship. to be compatible with the passive mode, the startagents is not set to 0. If the active mode is used at the beginning, we recommend that you set startagents to 0, disable Passive Mode

Ii. Server Configuration Adjustment:

Startpollers = 100

First, reduce the process of actively collecting data. The original process is more than 700.

Starttrapi pers = 200

Then, you can increase the number of processes that process the data pushed by agentd.

3. Adjust the Template

We recommend that you clone a template OS Linux template to modify it. The adjustments are as follows:

650) This. length = 650; "src =" http://s3.51cto.com/wyfs02/M00/4C/36/wKiom1Q48kiA3gVIAAI9T4EdOKk715.jpg "Title =" 1.jpg" alt = "regular"/> change the type of all items from the original "zabbix proxy" to "zabbix endpoint proxy (active )"

You only need a few simple steps to complete the active mode switch. After the adjustment, the server will not be stuck, the layers will not split, and the process will be less.
