{'author': 'Christian Wirtz', 'description': 'Agent-based monitoring of ZFS ARC (Adaptive Replacement Cache) usage on Linux hosts. The agent plug-in collects raw numbers from /proc/spl/kstat/zfs/arcstats and /proc/meminfo (no shell/awk/bc arithmetic, avoiding locale-dependent decimal-separator bugs); the server-side check derives the service state from three independently configurable percent levels (ARC vs. zfs_arc_max, ARC vs. RAM, hit ratio) plus an unconditional WARN on ARC memory throttling. On hosts without a ZFS ARC, the plug-in emits nothing, so no service is discovered there. Includes a check-parameter ruleset, an Agent Bakery ruleset + bakery plug-in for automated deployment, and graphing (perf-o-meter + graph). This is the agent-based + bakery successor of the former local check.', 'download_url': 'https://github.com/Gulaschcowboy/checkmk_extensions', 'files': {'cmk_addons_plugins': ['zfs_arc/agents/zfs_arc', 'zfs_arc/agent_based/zfs_arc.py', 'zfs_arc/rulesets/zfs_arc.py', 'zfs_arc/rulesets/agent_config_zfs_arc.py', 'zfs_arc/bakery/bakery_plugin_zfs_arc.py', 'zfs_arc/graphing/zfs_arc.py', 'zfs_arc/checkman/zfs_arc']}, 'name': 'zfs_arc', 'title': 'ZFS ARC cache usage (agent-based + bakery)', 'version': '1.0.1', 'version.min_required': '2.3.0', 'version.packaged': 'hermes', 'version.usable_until': None}
