Extending Vector with eBPF to inspect host and container performance.

Today we are excited to announce latency heatmaps and improved container support for our on-host monitoring solution — Vector — to the broader community. Vector is open source and in use by multiple companies. These updates also bring other user experience improvements and a fresher technology stack.

Here’s a quick summary of what’s new and improved.

Introducing BCC and eBPF visualisations

BCC BPF widgets

Andreas Gerstmayr has done fantastic work with developing a PCP PMDA for BCC, allowing BCC tool output to be read from Vector, and adding visualizations to Vector to view this data. Vector can now show these from BCC/eBPF:

  • Block and filesystem (ext4, xfs, zfs) latency heat maps
  • Block IO top processes
  • Active TCP session data such as top users, session life, retransmits ..
  • Snoops: block IO, exec()
  • Scheduler run queue latency

Integrated multiple host and container metrics

For a more complex set of use cases, being able to view metrics simultaneously from multiple containers on a host or both the container and the host may be necessary. You can now render charts from multiple hosts and containers on a single chart, and resize them so that it makes sense.

CPU across multiple hosts

Getting the latest

As usual, the quickest way to get started is to use the Docker container:

docker run \
  -d \
  --name vector \
  -p 80:80 \

You still need to load the agent software on each monitored host for the Vector dashboard to connect to.
