Cacti monitoring Tomcat server implementation process

1. First download the common monitoring template from the official website.

Generally, the tomcatstats-0.1.zip template is mostly used ,:

Http://forums.cacti.net/download/file.php? Id = 1, 12310,

Use wget download on a linux server, wget http://forums.cacti.net/download/file.php? Id = 12310, the following error is reported:

Connecting forums.cacti.net | 173.225.179.10 |: 80... already connected.

An HTTP request has been sent and is waiting for response... 301 Moved Permanently

Location: http://forums.cacti.net/[following to new URL]

You have redirected more than 20 times.

Can I enter a http://forums.cacti.net/download/file.php in Windows 7's google browser? Id = 12310 click "enter" to download, and then use the SecureFX client tool scp to connect to the linux server.

Then, the three files cacti_host_template_tomcat_server.xml,install.txt and tomcatstats. pl are decompressed.

2. Import the template on the website of the cacti master server

Open the website of the cacti Server:

Go to http://10.xx.1.xx/cacti/index.php-> Console-> Templates-> Import Templates, select the File Import (cacti_host_template_tomcat_server.xml) file, and select the Import button to load the tomcat template.
3 cacti server load atatstats. pl statistics script

Place the tomcatstats. pl obtained from tomcatstats-0.1.zip in the/var/www/html/cacti/scritps directory and grant the execution permission. <喎?http: www.bkjia.com kf ware vc " target="_blank" class="keylink"> Environment + PHA + Environment/JxNyz9s/Wyv2 + Environment/Y1sbMqLTys/Environment + cq + o7ogICA8L3A + PHA + Environment/Environment + PHA + Environment + o6zI58/Co7o8L3A + PHA + tomcat ''9ssspw' http-9444

?
You can also enter the above URL in the google browser of Windows 7, and many tomcat statistics will also appear, as shown below:

4. Modify the url of tomcat data retrieval in cacti.

Go to cacti ---> console ---> Data Input Methods ---> Tomcat Status

Modify fields in Input String

To: perl <path_cacti>/scripts/tomcatstats. pl

Note: replace the above username and password with the actual tomcat Administrator account and password.

The attachment of the manager account for which tomcat is to be enabled contains the description of Enable the Tomcat manager application, for example:

5. Configuration Adjustment of the web-side tomcat server

Add the following in tomcat/conf/server. xml:

<Service name = "Admin">

<Connector port = "9444" maxHttpHeaderSize = "8192"

MaxThreads = "150" minSpareThreads = "25" maxSpareThreads = "75"

EnableLookups = "false" disableUploadTimeout = "true"

AcceptCount = "100" scheme = "https" secure = "true"

ClientAuth = "false" sslProtocol = "TLS"/>

<Engine name = "Admin" defaultHost = "localhost">

<Realm className = "org. apache. catalina. realm. UserDatabaseRealm"

ResourceName = "UserDatabase"/>

<Host name = "localhost" appBase = "webapps"

UnpackWARs = "false" autoDeploy = "false"

XmlValidation = "false" xmlNamespaceAware = "false">

<Valve className = "org. apache. catalina. valves. FastCommonAccessLogValve"

Directory = "logs" prefix = "admin_access_log." suffix = ". txt"

Pattern = "combined" resolveHosts = "false"

FileDateFormat = "yyy-MM-dd"/>

<Context path = "/manager" cookies = "false"

DocBase = "server/webapps/manager" debug = "0"

Privileged = "true" reloadable = "false"/>

</Host>

</Engine>

</Service>

Then add in tomcat/conf/tomcat-users.xml

<Role rolename = "manager-gui"/>

<User username = "tomcat" password = "9 ssspw" roles = "manager-gui"/>

You can change the connection password for passwords and restart the tomcat service.

Go to the cacti server side and execute perl tomcatstats. pl 10. xx.3.xx: 9444 "tomcat ''9ssspw' http-9444 check statistics script to check whether tomcat data can be obtained, data is normal, as shown below:

The connection pool configuration problem is found after tracking:

Remove debug = "0.

Analysis: the debug function may be replaced by other attributes in tomcat 6.0.37.

6 Cacti tomcat monitoring options

Graph templates has four options in total, as shown below:

Click the monitoring item to connect to the system. The ERROR message "RRDTool Says: ERROR: invalid y-grid format" is displayed,

Solution:

Connect to * Edit Graph Template --> Tomcat-Connection Rate --> Unit Grid Value (-- unit/-- y-grid) in the upper-right corner. The default Value is 1, remove and change it to 0.

Similarly, you can leave the 1048576 value blank when Tomcat-Heap Statistics does not output a graph.

If the figure cannot be displayed within 10 minutes, you can continue to wait. It takes a long time to figure out the tomcat monitoring template. After three hours, the figure is shown as follows:

1) Tomcat-Connection Rate: Connection Efficiency

2) Tomcat-Heap Statistics: JVM Heap usage

3) Tomcat-Thread Statistics: Thread status

4) Tomcat-Throughput: Tomcat Throughput
