Cisco CDR Reporting & Analytics | Installation Notes

# Cisco Unified Border Element (CUBE)

Note this setup is surprisingly unlike how the CDR is collected from CUCM. We apologize for Cisco’s inconsistency.

### Preparation

Next you will need to set up an FTP server. CUBE and vCUBE cannot use SSH or SFTP, so the SFTP server you may have set up already to collect Callmanager’s CDR can not be used for the CUBE data.

On your FTP server, create a user and a new folder that the user can write files to. For our example setup, we will be using server 10.0.0.100, and a user user with password splunk. As our prefix for filenames, we will use cube_​.

Validation steps:

After this is set up, you should be able to confirm via a manual test that this user can upload a file to the configured directory. Remember to delete the test file(s) when you are done.

### Steps to configure the file accounting server

Log into the server used for file accounting with an account with administrative permissions. Then, run the below listed commands to set up gw-accounting to file, change the cdr-format to detailed”, configure the FTP server information, and tell the system to flush new data to file once per minute. Note the bold italic portions are ones you’ll change.

1. enable
2. configure terminal
3. gw-accounting file
4. cdr-format detailed
6. maximum cdrflush-timer 1
7. end

Be sure to change your server information in step 5 as appropriate.

Also in step 5 – be SURE to either use a different prefix from your cdr data so that they have names different from the cdr and cmr files, like cube_​” for the files, or use an entirely different folder structure so the cdr_​*, cmr_​* and cube_​* files are all either in different places. If they do not, there’s a possibility of bad things happening because you’ll have all your inputs fighting over these files, and they’ll ingest them incorrectly.

Note especially that this accepts many of the default settings for buffer sizes and the number of reattempts. We assume these will work in most moderately sized installations, but please check and confirm them for your own environment.

### Create a new Splunk input

We will now create a new batch” input for the CUBE CDR files, similar to the ones you created for CUCM CDR and CMR.

Important note: this input will be set up to delete the files from disk as they go into Splunk. If you need this to not happen, please see the notes at the end of this section.

All these steps happen in your FTP server’s Splunk Universal Forwarder’s configuration files:

1) Create the monitor input by adding this config to an inputs.conf file located at “\$SPLUNK_​HOME/​etc/​apps/​TA_​cisco_​cdr/​local/inputs.conf”. This file should exist already, but if it does not, you may need to create the folder local” and the file itself. Make sure the user Splunk runs under has permissions to this file and folder.

If your Universal Forwarder is on Windows, the contents of your inputs.conf will look like this:

[batch://D:\path\to\files\file_accounting\cube_*]
index = cisco_cdr
sourcetype = cube_cdr
move_policy = sinkhole


If your Universal Forwarder is on Linux or Unix, the input will look like this:

[batch:///path/to/files/file_accounting/cube_*]
index = cisco_cdr
sourcetype = cube_cdr
move_policy = sinkhole


NOTE: It is critical that no mistakes be made here. Only the path (after batch://”) and possibly the index need editing. All else should be left exactly as it is.

Make sure :

1. If your forwarder is on a Linux or Unix host, that you use appropriate slashes, i.e. “/​foo/​bar/​cdr_​*” vs C:\foo\bar\cdr_*”.
2. Make sure to match the format of the paths.
• Linux – Note the triple slashes at the front of the path – it’s batch://” then the path starting with the leading slash, “/​path/​to/​files/​”, hence three slashes.
• Windows – Full path goes here: it’s batch://” then your path, including drive letter, like E:\SFTP”, for batch://E:\SFTP\”.
3. That the index specified in both lines matches exactly the single index specified in the custom_​index” macro on the Search Heads’ apps.
• Index names in Splunk are case-sensitive. index = cisco_​cdr” is not the same as index = cisco_CDR”.
• If you used the default cisco_​cdr” index, then the above file snippets should work correctly as-is.
4. That cube_​*” is present on the end of the path.
5. That the sourcetype is cube_​cdr”.

NOTE: As mentioned above, this is a sinkhole input, and it will delete each file as it indexes it. Any existing csv files that exist in this directory will be indexed and deleted almost immediately, and any new files written to here will be indexed and deleted as they arrive. If you have other intentions for these files besides putting them in Splunk, please contact us, and we can help you come up with another solution.
