Agent Journaling

I'm sorry if this is a repost, but I searched and couldn't find anything similar.

Is there anyway, currently or in a future version, for agents to continue gathering data while the server is offline, then to upload it when the server returns so there are no gaps in the record?

Presently this is not possible.

The closest you can get would be to use a proxy, but again you have the challenge of what if the proxy goes offline.

Initially I thought BufferSize and BufferSend were for this purpose, but they are for reducing the number of TCP connections that need to be opened to the server.

Sure, it is already supported! If you use active checks, the data is buffered on agent side even if there are no comms. When Zabbix server is back, agent will start sending of the buffered data.

Parameters BufferSize and BufferSend controls size of the buffer.

Ooh! This was one of my worries with Zabbix (actually I'm in the process of implementing a HA server cluster to ensure Zabbix server is always available.)

I've just switched all my agent checks to active so I'm very glad to have read this

Are these checks buffered infinitely? Or will it buffer so many? If so many, is it possible to calculate how long the server can be off-line before results are "lost" ?
