After some Swap configuration changes metricbeat stop sending memory info I got any other type but memory info.
About an hour ago we made some changes in our server configuration and now we got this
The changes we made were to just stop using swap memory:
Then change the fstab file and comment out the swap lines and finally a cache clear:
sync; echo 1 > /proc/sys/vm/drop_caches
sync; echo 2 > /proc/sys/vm/drop_caches
sync; echo 3 > /proc/sys/vm/drop_caches
After this we stop recieving memory part. And before this everything was normal. When I start metricbeat it's sending memory info in JSON but all data comming from memory it's all 0s
