DstNet*values - 🌱 inlet: if available, use sFlow for
DstASPath - 🌱 docker: update Kafka UI image
This version introduces the ability to customize the data schema used by
Akvorado. This change is quite invasive and you should be cautious when
deploying it. It requires a restart of ClickHouse after upgrading the
orchestrator. It also takes some time to reduce the storage size for SrcPort
and DstPort.
The orchestrator automatically defines the TTL for the system log tables (like
system.query_log). The default TTL is 30 days. You can disable that by setting
orchestrator→clickhouse→system-log-ttl to 0.
- ✨ inlet: add
schema→enabled,schema→disabled,schema→main-table-only, andschema→not-main-table-onlyto alter collected data - ✨ inlet: add the following collected data (disabled by default):
SrcAddrNATandDstAddrNATSrcPortNATandDstPortNATSrcMACandDstMACSrcVlanandDstVlan
- 🩹 inlet: handle correctly interfaces with high indexes for sFlow
- 🩹 docker: fix Kafka healthcheck
- 🌱 inlet: improve decoding/encoding performance (twice faster!)
- 🌱 orchestrator: set TTL for ClickHouse system log tables and
exporterstable - 🌱 orchestrator: reduce storage size for
SrcPortandDstPort - 🌱 orchestrator: add
clickhouse→kafka→engine-settingsto configure additional settings for the Kafka engine - 🌱 common: Go profiler endpoints are enabled by default
There is a schema update in this version: you also have to restart ClickHouse after upgrading for it to pick the new schema.
This version also introduces a cache for some HTTP requests, notably those to
plot the graphs in the “Visualize” tab. The default backend is in-memory,
however the shipped akvorado.yaml configuration file is using Redis instead.
The docker-compose setup has also been updated to start a Redis container for
this usage. Use of Redis is preferred but on upgrade, you need to enable it
explicitely by adding console→http→cache in your configuration.
- ✨ console: cache some costly requests to the backend
- ✨ console: add
SrcNetPrefixandDstNetPrefix(as a dimension and a filter attribute) - ✨ inlet: add
inlet→flow→inputs→use-src-addr-for-exporter-addrto override exporter address - 🌱 console: add
limitandgraph-typetoconsole→default-visualize-options - 🌱 docker: published
docker-compose.ymlfile pins Akvorado image to the associated release - 🌱 docker: update Zookeeper and Kafka images (this upgrade is optional)
- ✨ console: add 100% stacked graph type
- 🩹 inlet: handle non-fatal BMP decoding errors more gracefully
- 🩹 inlet: fix a small memory leak in BMP collector
- 🩹 console: fix selection of the aggregate table to not get empty graphs
- 🩹 console: use configured dimensions limit for “Visualize” tab

console→database→saved-filtersto populate filters from the configuration file - 🩹 doc: durations must be written using a suffix (like
5s) - 🌱 docker: provider a tarball with essential files to install or upgrade a
docker-composesetup - 🌱 inlet: skip unknown AFI/SAFI in BMP route monitoring messages
- 🩹 inlet: fix SrcAS when receiving flows with sFlow
- 🩹 inlet: do not half-close BMP connection (a remote IOS XR closes its own end)
- 🌱 docker: split demo exporters out of
docker-compose.yml - 🌱 console: make the upper limit for dimensions configurable
(
console→dimensions-limit)
This release features a BMP collector to grab BGP routes from one or
several routers. The routes can be used to determine source and
destination AS (instead of using GeoIP or information from the flows)
but also the AS paths and the communities. Check inlet→bmp and
inlet→core configuration settings for more information.
- ✨ inlet: BMP collector to get AS numbers, AS paths, and communities from BGP PR #155
- ✨ inlet: add
inlet→snmp→agentsto override exporter IP address for SNMP queries - 🩹 inlet: handle sFlow specific interface number for locally originated/terminated traffic, discarded traffic and traffic sent to multiple interfaces
- 🌱 build: Docker image is built using Nix instead of Alpine
This release bumps the minimal required version for ClickHouse to
22.4. The docker-compose file has been updated to use ClickHouse
22.8 (which is a long term version). Moreover, Akvorado now has its
own organisation and the code is hosted at
akvorado/akvorado.

- 🌱 inlet: Kafka key is now a 4-byte random value making scaling less dependent on the number of exporters
- 🌱 demo-exporter: add a setting to automatically generate a reverse flow
- 🌱 docker-compose: loosen required privileges for
conntrack-fixer
SrcCountry/DstCountry were incorrectly filled in aggregated
tables. This is fixed with this release, but this implies dropping the
existing data (only the country information). See PR #61 for more
details.
- ✨ inlet:
inlet→core→default-sampling-ratealso accepts a map from subnet to sampling rate - ✨ inlet:
inlet→core→override-sampling-rateenables overriding the sampling rate received from a device - 🩹 orchestrator: fix
