It is often necessary to monitor the running status of memcached on the server, such as the number of cache queries and hit rate. ButThe memcached-tool is written in Perl in Linux, and I have never tried whether it can be used in windows. Later, I found a simple way to do this, that is, using telnet.
1. In Windows, connect to the memcached port. In the CMD command line, type telnet 192.168.1.1 11211 11211 as the port number bound to memcached.2. After connecting to the port, enter the

1) Tool DescriptionDstat is a tool for replacing Vmstat,iostat Netstat,nfsstat and Ifstat commands, and is an all-purpose system Information statistic tool. Compared with Sysstat, Dstat has a color interface, which is easy to observe when manually observing performance conditions; and Dstat support instant refresh, such as input Dstat 3, which is collected every three seconds, but the latest data will be refreshed every second. As with Sysstat, Dstat can also collect the specified performance re

You can also use its synchronous version path. existsSync (). The function is the same, but it does not call the callback function, but directly returns the result:
The Code is as follows:
