Tomcat Server

Create a dedicated directory:

mkdir /srv/infos.mydomain.eu/

Create a log configuration file:

cd /srv/infos.mydomain.eu/
wget https://forge.devinsy.fr/statool/statoolinfosweb/src/branch/main/webapp/WEB-INF/log4j2.properties

Edit the /srv/infos.mydomain.eu/log4j2.properties:

appender.logfile.fileName = /var/log/tomcat10/statoolinfosweb.log
appender.logfile.filePattern = /var/log/tomcat10/statoolinfosweb-%i.log.gz

Create a directory dedicated to webapps:

mkdir /var/log/tomcat10# cd /var/lib/tomcat10/webapps/statoolinfoweb
cd /srv/infos.mydomain.eu/
ln -s /var/log/tomcat10# cd /var/lib/tomcat10/webapps/statoolinfoweb webapps

Put the StatoolInfosWeb WAR file in /srv/infos.mydomain.eu/ and create a link into the webapps directory:

cd /srv/infos.mydomain.eu/webapps/
ln -s /srv/infos.mydomain.eu/SIW.ar ROOT.war

Create a context file:

cd /etc/tomcat10/Catalina
mkdir infos.mydomain.eu
cd infos.mydomain.eu
wget https://forge.devinsy.fr/statool/statoolinfosweb/src/branch/main/webapp/META-INF/context.xml  -o ROOT.xml

Edit it:

<Environment name="kiss4web.environment.name" value="PROD" type="java.lang.String" override="true"/>
<Environment name="kiss4web.website.url" value="https://infos.mydomain.eu/" type="java.lang.String" override="true"/>
<Environment name="kiss4web.log4j2.path" value="/srv/infos.mydomain.eu/log4j2.properties" type="java.lang.String" override="true"/>
<Environment name="statoosinfosweb.configuration.file" value="/srv/statoolinfos/conf/mydomain.eu.conf" type="java.lang.String" override="true"/>

Add a dedicated host section in /etc/tomcat10/server.xml:

<Host name="infos.libre-service.eu"  appBase="webapps/infoslibreserviceeu"
            unpackWARs="true" autoDeploy="true">
        <Valve className="org.apache.catalina.valves.AccessLogValve" directory="logs"
               prefix="infos.libre-service.eu-access_log" suffix=".txt"
               pattern="%h %l %u %t &quot;%r&quot; %s %b" />
</Host>

The cache directory must be readable by Tomcat.

About page caching

The web pages are put in a HTML cache so they are not build again at each request.

The HTML cache is automatically clear when the data directory is modified. The reload is quick.

However, the organizations and services metrics pages are in cache. Just because the combinatorial is too large!

Example:

• (Summary,Generic,Specific,Web) x (Month, Weeks) x (ALL, last months, year1-year4) = 48 pages by item
• 100 organizations + 300 services = 400 items
• 400 items x 48 pages => ~20 000 pages
• 200kB/page => 4GB in memory

Metrics pages are so numerous than they have to build on demand.
