Trisul AAA ingestor

The trisul_aaaing is the RADIUS AAA log ingestor utility. This is used to add user-id and other details to flow records.

This tool monitors a directory for AAA CSV log dumps, extracts them, and imports the data into a database, enabling the correlation of AAA user IDs and broadband service IDs with IPDR logs.

To see its capabilities and sample CRONTAB entry check the man page.

man trisul_aaaing 	

Dumping the AAA logs

The process is.

• Create a directory on the Trisul IPDR Server where you want to receive AAA dump files. Say this is /opt/ipdr/cdrlogs. This will be passed as the argument -d /opt/ipdr/cdrlogs to the trisul_aaaing process
• Write a script on the RADIUS system to periodically export the active and closed flows say every 1 hour. Typically each NAS will have its own file.
• The filename MUST include the timestamp in some manner. Ex - the file name can be radiusaaa0_CDRs2023-09-27_133000.csv where the timestamp is 2023-09-27_133000 or it can be netxstream-nas1-1740587653.csv where the number 1740587653 is a unix epoch timestamp.
• SFTP (Secure FTP) from the RADIUS server to the Trisul IPDR server say every 1 hour

File format

Out of the box Trisul IPDR supports the following file format

• File names of the form elite*YYYY-MM-DD_HHMMSS.csv - example elite-nas1-CDRs-2024-07-27_143000.csv
• Each record in the file contains this format

logTimestamp,acctStatusType,accountNumber,userName,framedIp,nasIp,nasId,sessionId,terminationCause,sessionTime,inputGigaWords,outputGigaWords,inputOctets,outputOctets,serviceName,RemoteID,serviceInfo

framedIp	5	the IPv4 address here it is the CGNAT 100.90.2.38
nasIp	6	the NAS IP address

Other formats

Trisul AAAING uses a LUA parser framework to support file formats other than the default one shown above. To use a different format, write a LUA parser for it.

You have to use the --lua-parser option to use a LUA script.

sample formats

The GitHub repository trisulnsm has a number of sample LUA scripts you can download modify and use https://github.com/trisulnsm/trisul-scripts/tree/master/lua/hub_scripts/radius-aaa

Using trisul_aaaing to ingest

Lets say the RADIUS CSV logs are dumped in a directory /ipdrdata/cdrlogs in the default elite format.

The directory will look like this. Each of the csv files contains AAA records.

Precision-3260:$ ls -l /ipdrdata/cdrlogs
total 627552
-rw-r--r-- 1 tris tris 55740696 Sep 28  2023 elite0_CDRs2023-09-27_133000.csv
-rw-r--r-- 1 tris tris 55400240 Sep 28  2023 elite0_CDRs2023-09-27_140000.csv
-rw-r--r-- 1 tris tris 56023402 Sep 28  2023 elite0_CDRs2023-09-27_143000.csv
-rw-r--r-- 1 tris tris 56893219 Sep 28  2023 elite0_CDRs2023-09-27_150000.csv
-rw-r--r-- 1 tris tris 56420276 Sep 28  2023 elite0_CDRs2023-09-27_180000.csv
-rw-r--r-- 1 tris tris 55133652 Sep 28  2023 elite0_CDRs2023-09-27_200000.csv

To ingest these files into the Trisul IPDR AAA database you can use the following command

trisul_aaaing -c /usr/local/etc/trisul-hub/domain0/hub0/context0/trisulHubConfig.xml \
      -d /ipdrdata/cdrlogs

Ingesting custom format

Lets say the RADIUS CSV logs are dumped in a directory /ipdrdata/cdrlogs in the a custom format say the Alepo vendor.

The directory will look like this. Each of the csv files contains AAA records.

Precision-3260:$ ls -l /ipdrdata/cdrlogs
total 20
-rw-rw-r-- 1 trisul trisul 6679 Feb 21 10:50 alepoaaa1_XISP_CDRs_2025-02-17_100001_34_004104.csv
-rw-rw-r-- 1 trisul trisul 3766 Feb 21 10:51 alepoaaa2_XISP_CDRs_2025-02-17_100002_35_002247.csv
-rw-rw-r-- 1 trisul trisul 3979 Feb 21 10:51 alepoaaa3_XISP_CDRs_2025-02-17_100001_36_002232.csv
-rw-rw-r-- 1 trisul trisul 2766 Feb 21 10:51 alepoaaa4_XISP_CDRs_2025-02-17_100001_37_002300.csv

Since they are not in default format you need a LUA parser. You can download the LUA parser radiusparse_alepo.lua from GitHub and save it to a directory say /root

Now you can run with the --lua-parser option

trisul_aaaing -c /usr/local/etc/trisul-hub/domain0/hub0/context0/trisulHubConfig.xml \
      -d /ipdrdata/cdrlogs --lua-parser /root/radiusparse_alepo.lua

Output

The trisul_aaaing takes the data inside of the CDR and are then integrated into the IPDR Flow data at query time.

There are other options you may want to add

• --move-out : after processing the file remove it from the directory
• --store-original : move the CSV files into the IPDR/ data directory inside the Trisul database slices.

See man trisul_aaaing for full description.

The log files are stored in the file t_aaaing.log . So see them

source /usr/local/share/trisul-hub/trisbashrc
cd.l 

Running via CRON

The command can be run from cron,

Command line Options

tip

Also see man trisul_aaaing for a full list with examples.

Option	Default value	Description
-c --config-file=FILENAME	/usr/local/etc/trisul-hub/domain0/hub0/context0/trisulHubConfig.xml	Specify the Trisul hub configuration file for the desired context. If omitted, the default context will be used, which is the typical configuration for most installations.
-F --in-format=ELITE	-	The input log file must be in CSV format. Currently, only a limited set of vendor codes are supported. For additional vendor code support or customization, please contact Unleash Networks.
-i --in-file= Filename	-	Process a single, specified AAA Log file in CSV format.
-d --in-directory=Directoryname	-	Specify the directory containing the AAA Log CSV files to be processed. The tool will automatically skip files that have already been processed, based on their timestamp.
--store-original		Optionally store the original log lines in the database, which can be useful for reconciliation and auditing purposes.
-s --store-hath-bb		Store an additional broadband subscriber ID extracted from the AAA log, which will be recorded as an extra column in the database, supplementing the existing user ID field.
-m --move-out		Store raw logs in the database for reconciliation and investigation, with optional archiving and removal of processed files.
--lua-parser		Utilize a LUA script to parse AAA CDR CSV files and extract custom attributes. A sample script, radiusparser.lua, is provided in /usr/local/share/trisul-hub/ for reference.
--skip-index		Skip creating the IP_AAA_INDEX during file creation to significantly speed up IPDR RADIUS CDR processing. Note that the index can be manually added later if needed.
--dry-run		Perform a simulated run that displays the processing order of CDR records without actually moving or modifying them.
--staging-dir=Directoryname		Specify a staging directory on a high-performance NVMe disk to facilitate bulk retroactive uploads of AAA records. This allows for efficient processing and subsequent transfer of records to slower archive disks.
--nas-scope		use this if the private IP Addresses are local to the NAS. Example if an ISP has several NAS devices each allocating the same private IP pool
