1.5

  • Merged netflow-asstatd.pl and sflow-asstatd.pl into one script so that it can handle NetFlow and sFlow sources concurrently (contributed by Wouter de Jong). Please note the following changes:
    • The sampling rate command line parameter (-s) has been removed. Instead, the sampling rate must now be specified for each link in the knownlinks file to avoid confusion with prior defaults. If you're using NetFlow without sampling, you need to add the sampling rate 1 to each link.
    • The command line parameter to set the sFlow listen port has been changed to -P to avoid a clash with the NetFlow port parameter (-p).

1.43

  • Add v6 data sources to add_ds_proc.pl
  • Remove closing tag from config.inc to prevent whitespace problems in gengraph.php
  • Fix security issue in gengraph.php/linkgraph.php
  • Updated asinfo.txt with data from whois.cymru.com.

1.42

  • Try harder to determine IP version for sFlow samples.
  • Add IPFIX support (contributed by Daniel Piekacz)
  • Add experimental NetFlow v5 support (contributed by Charlie Allom)
  • Fix handling of 64-bit counters for NetFlow v9

v1.41

  • Generate v6 RRD DS in contrib/sync_ds.pl too (spotted by Peter Hansen)
  • sFlow: fix creation of new RRDs when multiple entries with the same tag are present in the known links file (spotted by Michal Buchtik)
  • Add startup scripts for FreeBSD (contrib/freebsd) (contributed by Michal Buchtik)
  • Add support for setting the sampling rate per link in the knownlinks file.

v1.40

  • Add support for NetFlow v9 to netflow-asstatd.pl (sponsored by Xplornet Communications Inc.)
  • Add support for IPv6 (for NetFlow v9 and sFlow). Note: existing RRDs need to be upgraded (new data sources added for v6) for this to work. Enable $showv6 in www/config.inc to see separate graphs for IPv6.
  • Add support for 4-byte ASNs (NetFlow v9 and sFlow). Needs testing.
  • Add RRA for 1 month at 4 hour resolution to newly created RRD files.
  • Add links to PeeringDB and robtex (suggested by Steve Glendinning)
  • Fix AS-SET lookup on systems where the whois command returns additional lines.

v1.36

  • Fix creation of new RRDs when multiple entries with the same tag are present in the known links file (spotted by Michel Moriniaux)
  • Add feature to inspect all ASes in an AS-SET (automatic whois lookup). (contributed by Nicolas Debrigode)
  • Updated asinfo.txt with data from whois.cymru.com.

v1.35

  • Allow hyphens in link names. (contributed by Gareth Campling)
  • Smooth I/O burstiness and reduce overall IOPS requirements by flushing only 10% of the cache every 25 seconds (instead of the entire cache at once every 60 seconds). (contributed by James A. T. Rice)

v1.34

  • Fix for NaN detection in rrd-extractstats.pl for 64-bit Perl versions (contributed by Benjamin Schlageter)
  • Skip missing data sources in rrd-extractstats.pl to avoid abort if new data sources are added but the RRDs are not updated.

v1.33

  • Fix for multiple entries with the same tag in the knownlinks file (e.g. for LACP) (contributed by Michal Buchtik)
  • Added sync_ds.pl script to contrib directory, which can synchronize the data sources of RRD files with the tags defined in the knownlinks file (contributed by Michal Buchtik)
  • sflow-asstatd.pl now uses the agent IP instead of the UDP source address - this makes it behave properly when a proxy is being used (contributed by Michel Moriniaux)

v1.32

  • Fix add_ds.sh to support new directory structure (contributed by Sergei Veltistov)
  • Fix PHP warnings and move $ntop to config.inc (contributed by Michal Buchtik)

v1.31

  • Set memory_limit to 256 MB in PHP pages (suggested by Steve Colam steve@colam.co.uk).
  • Allow NetFlow aggregation version 0 as well as 2 to make NetFlow exports from Juniper routers work (suggested by Thomas Mangin thomas.mangin@exa-networks.co.uk).
  • Updated asinfo.txt with data from whois.cymru.com.

v1.3

Change your start script accordingly...

  • Changes by Steve Colam steve@colam.co.uk:
    • ...-asstatd.pl now accepts parameters (UDP listen port, sampling rate etc.) on the command line; Mind the new command line syntax when upgrading!
    • hierarchical RRD structure for more efficient storage (one directory per low byte of AS number); Use tools/migraterrdfiles.pl to move your RRD files when upgrading!
    • ...-asstatd.pl now re-reads known links file upon SIGHUP
  • Added contrib/generate-asinfo.py script to generate AS list from WHOIS data (contributed by Thomas Mangin thomas.mangin@exa-networks.co.uk).
  • Moved site-specific parameters of www frontend to config.inc.
  • New flag images from famfamfam.com.
  • Updated asinfo.txt.

v1.2

  • Support for sFlow (through sflow-asstatd.pl); fix for link names with upper-case characters
  • Allow inbound/outbound in graphs to be swapped (via option in www/config.inc)

v1.1

  • Fix for a potential race condition surrounding $childrunning (reported by Yann Gauteron; experienced on a Linux system)

v1

  • Initial release
