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/

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

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"
|

|
|
### StatoolInfos
|
|
|
|
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.
