```
apt-get install openjdk-17-jre-headless
```

Download the last release: `https://forge.devinsy.fr/statool/statoolinfos/releases` and unzip the package. 

The `srv/` directory is a example of deployment tree:

```
srv/
srv/statoolinfos
srv/statoolinfos/bin
srv/statoolinfos/bin/refresh
srv/statoolinfos/bin/probe
srv/statoolinfos/bin/uptime
srv/statoolinfos/bin/statoolinfos.sh
srv/statoolinfos/bin/crawl
srv/statoolinfos/conf
srv/statoolinfos/conf/sample-probe-http.conf
srv/statoolinfos/conf/log4j2-default.properties
srv/statoolinfos/conf/sample-probe-minetest.conf
srv/statoolinfos/conf/sample-federation.conf
srv/statoolinfos/conf/sample-probe-qrcode.conf
srv/statoolinfos/cache
srv/statoolinfos/statoolinfos-cron.log

Then, move the `statoolinfos.jar` file in `/srv/statoolinfos/bin/`.

Create link:

```
cd /srv/statoolinfos/bin/ ; ln -s statoolinfos.sh statoolinfos
```

Edit script in `/srv/statoolinfos/bin/` to target your federation configuration file.


In case of bad language output, add these lines on top of cron file:

```
LANGUAGE=en_EN.UTF8
LC_ALL=en_EN.UTF-8
```

## Simple federation configuration file

Example of `libre-service.eu.conf`:

```
# [Configuration] conf + organization + services + machines + metrics
conf.class=federation
conf.protocol=StatoolInfos-0.6.0

conf.crawl.input=https://www.libre-service.eu/.well-known/statoolinfos/libre-service.eu.properties
conf.crawl.cache=/srv/statoolinfos/cache/

```

The field `input` gives the federation properties URL file. Reminder, the StatoolInfos Protocol  requires that the federation properties file is exposed on the Web.

The field `cache` gives local directory used as data cache.


## Crawl

The `statoolinfos crawl` command loads the federation configuration file, then downloads the federation properties file and download all files set in.

In case of use with StatoolInfosWeb, never forget to give read permissions to Tomcat server. So, create a dedicated script would help.

Example of script `/srv/statoolinfos/bin/crawl`:

```
#!/bin/bash

echo "========== CRAWL at $(date  --iso-8601=seconds)" 
cd $(dirname "$0")
./statoolinfos crawl ../conf/federation.conf
chmod -R g+r /srv/statoolinfos/cache
chgrp -R tomcat /srv/statoolinfos/cache
```

Example of cron configuration `/etc/cron.d/statoolinfos`:

```
4 * * * * root /srv/statoolinfos/bin/crawl >> /srv/statoolinfos/statoolinfos-cron.log
```

Adjust your frequency according to your need. In case of large federation, once an hour is a good compromise.

## Uptime

The `statoolinfos uptime` command is very useful to collect the uptime of services. It's just to share  which services are down and since how many time. It is not a monitoring feature because an one hour check is enough for this. Actually, only website are checked.

In case of use with StatoolInfosWeb, never forget to give read permissions to Tomcat server. So, create a dedicated script would help.

Example of script `/srv/statoolinfos/bin/uptime`:


```
#!/bin/bash

echo "========== UPTIME at $(date  --iso-8601=seconds)"
cd $(dirname "$0")
./statoolinfos uptime ../conf/federation.conf
chmod -R g+r /srv/statoolinfos/cache
chgrp -R tomcat /srv/statoolinfos/cache
```

Example of cron configuration `/etc/cron.d/statoolinfos`:

```
4 * * * * root /srv/statoolinfos/bin/uptime >> /srv/statoolinfos/statoolinfos-cron.log
```

One check per hour is a good idea. In the uptime page, the mouse over a yellow status icon show the list of the check results.

In case of crawl, uptime and probe cron on the same computer, you can have different cron frequencies. It is better to have only script for call all them:

```
#!/bin/bash

echo "========== REFRESH at $(date  --iso-8601=seconds)" 
cd $(dirname "$0")
./probe
./crawl
./uptime
#./htmlize
chmod -R g+r /srv/statoolinfos/cache
chgrp -R tomcat /srv/statoolinfos/cache

```

And so your cron can be like that:

```
4 0,12,23 * * * root /srv/statoolinfos/bin/refresh >> /srv/statoolinfos/statoolinfos-cron.log
4 1-11,13-22 * * * root /srv/statoolinfos/bin/uptime >> /srv/statoolinfos/statoolinfos-cron.log
```


## Htmlize command **removed**

The `statoolinfos htmlize` command is removed since 2024-07.

As a reminder, the htmlize command generated absolutely all the pages needed for a static website.

As the number of pages generated became too large (> 10000 with 100 organizations), the decision was made to separate the html valuation into a separate project, StatoolInfosWeb.

A dynamic web site allows to generate page only when it is necessary. 


## Probe (Generate metrics files)

###  Basics
The `statoolinfos probe` command computes data sources to generate metric properties files. In case of already existings file, the data are loaded before the computation to be updated.

In case of use with StatoolInfosWeb, never forget to give read permissions to Tomcat server. So, create a dedicated script would help.

Example of script `/srv/statoolinfos/bin/probe`:

```
#!/bin/bash

echo "========== PROBE at $(date  --iso-8601=seconds)" 
cd $(dirname "$0")
./statoolinfos probe -previousday ../conf/
chmod -R g+r /srv/statoolinfos/cache
chgrp -R tomcat /srv/statoolinfos/cache
```

Note: set a specific configuration file is not necessary, because you can have multiple service to probe. Only probe configuration files will be manage.

Example of cron configuration `/etc/cron.d/statoolinfos`:

```
4 * * * * root /srv/statoolinfos/bin/probe >> /srv/statoolinfos/statoolinfos-cron.log
```

### HTTP Server configuration

The probe feature generates properties files to expose on web. StatoolInfos protocol recommends to follow the well-known convention.

Example of `/etc/apache2/statoolinfos.conf` generic configuration file:
```
  Alias "/.well-known/statoolinfos/" "/srv/statoolinfos/well-known/statoolinfos/"
    <Directory "/srv/statoolinfos/well-known/statoolinfos">
        Options +Indexes
        Require all granted
    </Directory>
```

Example of include directive in `/etc/apache2/sites-enabled/myservice.conf`:
```
<VirtualHost *:443>
			[…]
        Include statoolinfos.conf
        […]
</VirtualHost>
```

### Sample  configuration file

Create a configuration file `/srv/statoolInfos/conf/foo.bar.org.conf`:

```
conf.probe.types=<metrictype1>, <metrictype2>
conf.probe.metrictype1param1.file=<value>
conf.probe.metrictype1param2.file=<value>
conf.probe.metrictype2param1.file=<value>
conf.probe.metrictype2param2.file=<value>
conf.probe.target=/srv/statoolinfos/well-known/statoolinfos/foo.bar.org-metrics.properties
```

Generate the metric file for the first time:

```
/srv/statoolinfos/bin/statoolinfos probe -full /srv/statoolinfos/conf/foo.bar.org.conf
```

Create a cron file in `/etc/cron.d/statoolinfos` to update the metric file everyday:
```
4 0,12 * * * root /srv/statoolinfos/bin/statoolinfos probe -previousday /srv/statoolinfos/conf/foo.bar.org.conf >> /srv/statoolinfos/cron.log
```

In case of several configuration files, just set the configuration directory (without wildcard):
```
1 0,12 * * * root /srv/statoolinfos/bin/statoolinfos probe -previousday /srv/statoolinfos/conf/ >> /srv/statoolinfos/cron.log
```

Warning: in previous day mode, the metrics generated are overwrited for the last month, the last week and the last day. So, **six weeks in logs are required**.

```

Warning: to have month metric values, you have to set **retention log to 7 weeks or 50 days** in Nginx or Apache logrotate configuration.

For Nginx, éditer le fichier `/etc/logrotate.d/nginx` :

```
/var/log/nginx/*.log {
    weekly
    missingok
    rotate 7
```

For Apache, éditer le fichier `/etc/logrotate.d/apache2` :

```
/var/log/apache2/*.log {
    weekly
    missingok
    rotate 7
```

### Cron all task

A situation you will encounter is the need to do several tasks from the same machine. In this case, avoid multiple cron in the same time. Put all in Bash script and call it with only one cron.

Example:

```
4 0,12,23 * * * root /srv/statoolinfos/bin/refresh >> /srv/statoolinfos/statoolinfos-cron.log
4 1-11,13-22 * * * root /srv/statoolinfos/bin/statoolinfos uptime /srv/statoolinfos/conf/libre-service.eu.conf >> /srv/statoolinfos/statoolinfos-cron.log

```
