For many self-implemented services, many people prefer to use a dedicated monitoring process to monitor their own services. To prevent the monitoring process from collapsing, they even use classic dual-process monitoring. Not to mention anything else, writing and debugging this dual process is enough for me to have a pot of tea. It is a tough task for me to write bugs like this. Even one day, I will not write any bugs, but you will not be able to go t

Each individual containing a A process with existing process information has some specialized links available, and any process in the system has a separate self-linking point to the process Information, which is useful for getting command-line information from the process.2: System Information: If you need to know the entire

network (unless you are using a vro ). When you run the tcpdump command, it sets the TCP/IP stack to promiscuous mode. This mode can receive all the data packets and display them effectively. If we only care about the communication of our local host, one way is to use the "-p" parameter to disable promiscuous mode, and another way is to specify the host name: Tcpdump-I eth0 host hostname In this case, the system only monitors the communication data

Use SNMP and Cacti to monitor Linux servers SNMP (Simple Network Management Protocol) is used to collect internal data, such as load, disk status, and bandwidth. Network monitoring tools such as Cacti use this data to generate icons for monitoring purposes. In a typical Cacti and SNMP deployment, one or more SNMP-enabled devices and an independent monitoring server are used to collect SNMP feedback from tho

Use logwatch to monitor log files in Linux Linux operating systems and many applications create special files to record their running events. These files are often called "logs ". These system logs or specific application log files are essential tools for understanding the behavior of operating systems or third-party
