Release 0.0.8

• Add option to influx to log to a backup file in case the database is unavailable
• Calculate %downtime since startup if no ping ever succeded
• Wait instead of shutting down when no default gateway was found (may happen if the service is started too early)
• Fixed missing decimal places for pings greater than 99ms
• Report targets which we stopped pinging
  • may happen if we're stuck on resolving a domain name
• Shut down after pressing ctrl + c
• Support for %sut (start uptime) placeholder
• Loglevels are now per target
• Report if there is a dependency loop
• Influx now has a timeout (10s for connecting; in total 30s for the request to be processed by the server)
• Influx: support for ipv6
• Cache which replacements need to be done in placeholders (command.cmd, log.message, influx.linedata)
• Calculate time taken for resolving hostnames (debug output)
• down-new also supports delay
• %sdt is now set when the first ping fails (if num_pings is greater than 1)

Release 0.0.7

• Pings now follow period more closely (and no longer shift)
  • Previously some shift occured as we waited period time between pings (and did not include actions which may take some time)
• timeout for the command action
• action influx for inserting data into InfluxDB
• %timestamp is replaced with the unix timestamp
• Allow development without gateway
• datetime_format (defined in srd.c) will replace %%ms (really double percentage sign) with the milliseconds of the current time
• Fix no message when loglevel is invalid
• Potential performance improvements
• targets can now be IPv6 addresses
• New setting header for action log (usefull for creating CSV files)

Release 0.0.6

• Breaking: down-again, up-again renamed to down-new andup-new
• Own ping implementation (running as root is no longer needed to ping)
  • We now use approximately 2.5 times less CPU time (userspace and kernel times)
• %status placeholder for success or failed depending if the ping was answered or not
• datetime_format (from srd.conf) is regarded when printing the current time in stdout
• Event down-again which runs if a previous ping succeeded and now fails
• Fixed potential very rare race condition when printing
• Fix %lat_ms not always beeing replaced
• Make datetime_format optional in srd.conf
• up-new actions are triggered at startup
• %uptime placeholder
• Update README.md
• Support %ip placeholder in log.path

Release 0.0.5

• new ERROR loglevel (nothing logged regarding connections)
• Fix free when using a reboot action
• Added datetime_format as a configuration in srd.conf
• Action log now supports user which sets the owner of the logfile (only on creation)
• Added %downtime placeholder for the downtime in days, hours, minutes and seconds

Release 0.0.4

• Fix some memory not getting deallocated
• Fix host beeing reported as up due to a race condition when pinging
• Do not stop service if we cannot create a ping object
• New action: log to file (see README.md for documentation)
• up-again variables: for %sdt (start downtime) and %now
  • available in log.message and command.cmd

Release 0.0.3

Changes in this release

• Do not start if gateway IP cannot be determined
• Do not start if a dependency is non-existent
• systemd-service: run srd after network-online.target
• configure num_pings (number of pings sent)
• add configuration 'run_if' to actions to define when it is run
  • down, up, always, up-again
• print latency in command with %lat_ms

Initial release

Initially supported features are:

• Execute the following actions if a ping fails to a certain host for a given amount of time (See README.md#Configuration):
  • restart another systemd-service
  • restart the system
  • execute custom command as specific user
