ssp-loganalysis.php

The script is applicable to those who have enabled the Authentication Process Filter "statistics:StatisticsWithAttribute" on the Identity Provider.

To determine if your SimpleSAMLphp instance has the required Authentication Process Filter enabled, required by this HOWTO, check your metadata/saml20-idp-hosted.php and find out the following authproc:

45 => [
    'class' => 'core:StatisticsWithAttribute',
    'attributename' => 'realm',
    'type' => 'saml20-idp-SSO',
],

Example of a log line considered:

Feb  7 12:32:12 ssp-idp simplesamlphp[27612]: 5 STAT [46ff6971c4] saml20-idp-SSO https://sp.aai-test.garr.it/shibboleth https://ssp-idp.aai-test.garr.it/simplesaml-212/module.php/saml/idp/metadata NA

What remains to be done to produce the required statistics is:

  1. Split the log lines present in the single file /var/log/simplesamlphp.log or /var/log/simplesamlphp.stat into individual files, one for each month (e.g., simplesamlphp-YYYY-MM.log or simplesamlphp-YYYY-MM.stat).

  2. Set the constant SSP_HOME_DIR within the script.

At this point, executing the script for each month will yield:

php ssp-loganalysis.php simplesamlphp-2023-01.log > /tmp/idp_$(dnsdomainname)_2023_01_sso_stats.json

php ssp-loganalysis.php simplesamlphp-2023-02.log > /tmp/idp_$(dnsdomainname)_2023_02_sso_stats.json

This will produce files like idp_garr.it_2023_01_sso_stats.json in the following JSON format:

{
    "stats": {
        "logins": 17,
        "rps": 1,
        "ssp-version": "1.19.8"
    },
    "logins_per_rp": {
        "https://sp.aai-test.garr.it/shibboleth": 17
    }
}

These files can be sent to IDEM as an attachment.
