1) You can view basic information about a process, such as CPU, memory, parent process, execution path, and creator. 2) stop the process and create a new process. 3) You can configure the target process and set the refresh speed. Finally: (Some code is provided below. The rest are like Process Creation and suspension, which can be easily implemented using the process class) 1) Use WMI to get the parent process ID and process creator (Note: The content

Now there are a lot of people using Zabbix, but I think if the number of server monitoring is not much, the old monitoring system Nagios is very good. Nagios Alarm function is very powerful, and the program is small, resource footprint. Nagios default does not support drawing, you can match cacti, but build more complex. Individuals are still accustomed to using Pnp4nagios. Nagios and Pnp4nagios A key installation script reference to my Github:https://github.com/zhangnq/nagios/tree/master/setup

Use Ganglia to monitor Hadoop and HBase Clusters 1. Introduction to Ganglia Ganglia is an open-source monitoring project initiated by UC Berkeley designed to measure thousands of nodes. Each computer runs a gmond daemon that collects and sends metric data (such as processor speed and memory usage. It is collected from the operating system and the specified host. Hosts that receive all metric data can displa

Through them you can implement synchronization objects such as Autoresetevent,manualresetevent, while also in the efficiency and memoryThe use of

you get started? It is actually not that difficult. As long as you can use JNDI and read javadocs, you will find it quite easy to manipulate mbeans. In the following sample code, we will show you how to obtain the mbean home interface and JDBC pool of the local server. Mbeanhome home = (mbeanhome) New Initialcontext (). Lookup (mbeanhome. local_jndi_name ); Set pools = home. getmbeansbytype ("jdbcconnectionpool "); The above Code provides mbean con
