Check wildfly-version

Overview

Checks if a newer version of WildFly is available by comparing the installed version, queried from the HTTP management API, against the latest release on the GitHub releases API. Alerts when the installed version is outdated. The plugin supports both standalone mode and domain mode.

Important Notes:

  • --username and --password of a management user are required (same ManagementRealm user the other WildFly plugins use).
  • Only stable releases are considered. GitHub's "latest release" endpoint returns the most recent non-prerelease, non-draft release, and WildFly flags its .Beta, .CR and .Alpha tags as prereleases, so they are skipped.
  • The comparison ignores the version qualifier (.Final), so 40.0.0.Final is compared as 40.0.0.

Data Collection:

  • Queries the WildFly management API for product-version (falls back to release-version if product-version is not available)
  • Authenticates via HTTP Digest Auth (--username, --password)
  • Queries the GitHub releases API for the latest release of wildfly/wildfly
  • Caches the latest version information locally to reduce API calls (default: 24 hours)

options:
  -h, --help            show this help message and exit
  -V, --version         show program's version number and exit
  --always-ok           Always returns OK.
  --cache-expire CACHE_EXPIRE
                        The amount of time after which the credential/data
                        cache expires, in minutes. Default: 24
  --insecure            This option explicitly allows insecure SSL
                        connections.
  --instance INSTANCE   WildFly instance (server-config) to check when running
                        in domain mode.
  --mode {standalone,domain}
                        WildFly server mode. Default: standalone
  --no-perfdata         Suppress the performance data section from the output.
                        The status message and the exit code are unaffected,
                        so alerting keeps working while trending data is
                        dropped.
  --no-proxy            Do not use a proxy, not even one the environment
                        names. Overrides `--proxy`.
  --node NODE           WildFly node (host) when running in domain mode.
  -p, --password PASSWORD
                        WildFly management API password.
  --proxy PROXY         Proxy to reach the target through. The scheme defaults
                        to `http` when omitted. Overrides the proxy the
                        environment names (`http_proxy`, `https_proxy`,
                        `all_proxy`) together with the exceptions it lists in
                        `no_proxy`, and is itself overridden by `--no-proxy`.
                        Without either parameter the environment applies.
                        Credentials belong into the environment variable
                        rather than here, because a command-line argument is
                        visible to every user on the host. Example:
                        `--proxy=http://proxy.example.com:3128`.
  --timeout TIMEOUT     Network timeout in seconds. Default: 8 (seconds)
  --url URL             WildFly management API URL. Default:
                        http://localhost:9990
  --username USERNAME   WildFly management API username. Default: wildfly-
                        monitoring
