1 Synchronization of monitoring configuration

The proxy configuration update is incremental. During a configuration sync only those entities are updated that have been changed; if there has been no change, nothing is sent. This approach allows to save resources and set a smaller interval (almost instant) for the proxy configuration update.

Proxy configuration changes are tracked using revision numbers. Only entities with revisions larger than the proxy configuration revision are included in configuration data sent to the proxy.

The entities for a configuration sync are as follows:

• If a regular expression is changed, all regular expressions will be synced.

An exception are the host macros which are sent also if anything on the host has been changed.

The command on the proxy will also initiate an incremental update.

Note that a full configuration sync will take place on a proxy start/restart, HA failover, if the session token has changed, or if the configuration update failed on the proxy, for example, if the connection was broken while receiving configuration data.

Note that ProxyConfigFrequency is:

• proxy parameter for active proxies

On active proxies ProxyConfigFrequency is a new parameter since Zabbix 6.4 and must be used instead of the now-deprecated ConfigFrequency.

If both ProxyConfigFrequency and ConfigFrequency are used, the proxy will log an error and terminate.
