Breaking release 0.5.0

Breaking change

• Project was renamed to xmpp-blackbox-exporter. The docker images now live at https://hub.docker.com/r/xsfjonas/xmpp-blackbox-exporter

Bugs fixed

• Disabled use of SCRAM-*-PLUS to work around https://github.com/mellium/xmpp/issues/46

Feature release 0.4.0

New features

• Support for exporting the IBR error condition (if IBR failed with an IQ error), see #10

Bug fixes

• Fix panic if IBR fails with an IQ error, also #10

Bugfix release 0.3.1

Docker image tag: xsfjonas/prometheus-xmpp-blackbox-exporter:0.3.1

Bug fixes

• Docker image was unbuildable due to outdated go version.

Feature release 0.3.0

New features

• Support for probing via IBR (#6)
• Support for gathering SASL and Dialback information for s2s probes
• Support for checking SASL/Dialback offerings for s2s probes, just like c2s probes can already for SASL
• Support for configuring the from attribute of the stream header in s2s probes (#7)

Breaking changes

• The s2s probe config now requires a from field which specifies the value of the from attribute in the stream header. This needs to be a valid bare domain JID, though it doesn’t have to resolve to anything. (#7)

Bug fixes

• Fix invalid stream from in s2s probes (#7)

Bugfix release version 0.2.3

Fixed bugs

• Panic when no proper IQ reply is received in time

Bugfix release version 0.2.2

Fixed bugs

• Goroutine leak with the ping prober (see #4)

Bugfix release version 0.2.1

Fixed bugs

• Fix file descriptor leaks which eventually turn the exporter useless (too many open files)

Feature release version 0.2.0

New features

• Export duration metrics for connection phases (connect, starttls) analogous to the official blackbox exporter
• Support for IQ ping prober: Authenticates using password-based SASL to a provisioned account and issues a XEP-0199 ping. Exports round-trip time, auth connection phase duration metric and allows on matching on success and/or error types.
