I am using Icinga2 in top down config sync mode. What i see is a lot of data gets exchanged between the master and the client due to heartbeat and JSONRPC pings. This results to a lot of network out data usage. I have limited data on the Client machines. . As i can see heartbeat and other intervals are hardcoded in the source code.
Please suggest a way to reduce the data usage. I have increased the check interval to 6 minutes and the data usage is around 800-900 KB per hour.
