Monitoring, backup, > something else? Is there a source available. Checkmk, formerly Check_MK, is a monitoring software[1]. I am using the Checkmk Raw Edition (CRE) open-source. Per default it gets data from an agent on a host with connect to 6556/tcp every 60 seconds. All counters are fetched in one connect, nothing is sent to the host. The agent for Linux is one big bash script[2]. The deb with the agent brings systemd integration: -------------------------------------------- $ cat "/etc/systemd/system/check_mk@.service" # systemd service definition file [Unit] Description=Check_MK [Service] ExecStart=/usr/bin/check_mk_agent KillMode=process User=root Group=root StandardInput=socket -------------------------------------------- $ cat /etc/systemd/system/check_mk.socket # systemd socket definition file [Unit] Description=Check_MK Agent Socket [Socket] ListenStream=6556 Accept=true [Install] WantedBy=sockets.target -------------------------------------------- With check_mk.socket started, SUnreclaim and vm_area_struct are growing endlessly. So I will investigate the checkmk agent. > Reco Reco, Thank you for your explanations and bumping me in the right direction.
