Common configuration of Tomcat Connector elements (max connections, etc)

In Tomcat server. XML, there are similar:

<Connector port="8080" protocol="HTTP/1.1" connectionTimeout="20000" redirectPort="8443" maxSpareThreads="750" maxThreads="1000" minSpareTHreads="50" acceptCount="1000"  maxProcessors="1000"   URIEncoding="gbk" useBodyEncodingForURI="true"/>

Configuration, where:

Acceptcount = "1000" Maximum number of accepted connections

Maxprocessors = "1000" Maximum number of active threads

Port = "8080" service port

Protocol = "HTTP/1.1" service protocol

Connectiontimeout = "20000" timeout time in MS

When the redirectport = "8443" redirection port requires secure communication, the customer request will be forwarded to the SSL redirectport

Maxthreads: the maximum number of threads that can be created by Tomcat. Each thread processes a request. maxthreads determines the maximum thread threshold value of Tomcat.

Minsparethreads: Minimum number of backup threads and number of initialization threads at Tomcat startup;

Maxsparethreads: Maximum number of standby threads. Once the created thread exceeds this value, Tomcat will close socket threads that are no longer needed;

Uriencoding = "GBK" sets the default transcoding format of Tomcat

View the instructions for $ tomcat_home/webapps/tomcat-docs/config/http.html, which are described as follows:
Uriencoding: This specifies the character encoding used to decode the URI bytes, after % XX decoding the URL. if not specified, ISO-8859-1 will be used. that is to say, if you do not set uriencoding, Tomcat by default is based on the ISO-8859-1 URL Decoding, ISO-8859-1 does not include Chinese characters, so the Chinese characters must not be correctly parsed.

How can I check the number of connections of current tomcat?

Assume that two Tomcat instances are enabled on the server, listening to ports 8040 and 8050 respectively.

Netstat-Na | grep estab | grep 8040 | WC-l

Netstat-Na | grep estab | grep 8050 | WC-l

The sum of the two is the number of connections to all Tomcat servers.
