This check will monitor the *electrical power* and the *state* of Power Supply Inputs from Extreme Network Switches. It is an **enhanced replacement** for the original Checkmk check *netextreme_psu_in*. > This plugin requires at least Extreme Networks' firmware version 30.x. It has not been tested with earlier versions. > This plugin adds the new "Extreme Power Supply Input" rule. After installation, the old rules named "Parameters for input phases of UPSs and PDUs" will no longer be effective. You must manually migrate them to the new "Extreme Power Supply Input" rule set. ### Improvements over the original check * More detailed state handling: instead of only ‘OK’ or ‘not detected’, this check distinguishes between Powered On, Powered Off, and Failed. * Flexible configuration: * "Powered Off" and "Failed" can be mapped to the desired Checkmk states (default: `CRIT`). * Upper power consumption thresholds can be adjusted in WATO.

This check will monitor the *rx_signal_power* and the *tx_signal_power* of optical modules (SFPs) from Extreme Network Switches. > This plugin requires at least Extreme Networks' firmware version 30.x. It has not been tested with earlier versions. > There is currently a bug in Extreme Networks' firmware. The "etsysEntitySfpSensorState" returns a value of 6 (highAlarm) instead of 4 (normal). This error only occurs in SNMP queries and not in the CLI. To resolve the issue, you need at least firmware version v31.7.1.4-patch1-77 or v32.3.x.

This check will monitor the *memory usage* of Extreme Networks Switches.

This special agent will monitor the APs, Sites and WLANs from the ExtremeCloud IQ Controller. > This Special Agent monitors the on-premises solution, the "[ExtremeCloud IQ Controller](https://www.extremenetworks.com/products/wi-fi-management/extremecloud-iq-controller/extremecloud-iq-controller)". Please do NOT confuse this with "ExtremeCloud IQ", a cloud solution.

This MKP is an early version and not final yet. Feedback, suggestions, and improvements are very welcome. The VMware Avi Special Agent monitors: - Alerts - Certificates - Clouds - Controller clusters and nodes - Pools - Service Engines using piggyback data - Virtual Services The package includes configurable monitoring rules, performance metrics, graph definitions, and a preconfigured dashboard for VMware Avi environments. **When upgrading from version 0.2.0, existing VMware Avi Special Agent and Virtual Service rules must be deleted before the update and recreated afterward. Version 0.2.0 also contains a severe parsing error and should no longer be used.** For installation instructions, configuration details, monitored metrics, upgrade notes, and the complete changelog, see the linked GitHub repository.

This check monitors the stability of Spanning Tree Protocol (STP) domains on Extreme Networks switches. The plugin evaluates topology changes and can detect unstable Layer 2 topologies caused by flapping links, unstable uplinks, loops, or misconfigured edge ports. > This plugin requires at least Extreme Networks' firmware version 30.x. It has not been tested with earlier versions.

This check monitors voltage sensors in Check Point firewalls. It is an **enhanced replacement** for the original Checkmk check *checkpoint_voltage*. > This plugin normalizes voltage sensor names during service discovery. As a result, existing services may be renamed (for example, Voltage Voltage 1V2 becomes Voltage 1V2). After upgrading from the original checkpoint_voltage check, a service discovery should be performed on affected hosts to remove obsolete services and create the new ones. See on github for detail. ### Improvements over the original check - Configurable state handling: - Out-of-range conditions can be mapped to the desired Checkmk state (default: `CRIT`) - Sensor reading errors can be mapped to the desired Checkmk state (default: `UNKNOWN`) - Optional performance data: - Voltage values can be exported as performance data - Enables metric collection and graphing in Checkmk - Improved service naming: - Removes redundant occurrences of "Voltage" from sensor names - Prevents duplicate service names such as `Voltage Voltage 0V99`

This check monitors fan sensors in Check Point firewalls. It is an **enhanced replacement** for the original Checkmk check *checkpoint_fan*. >This plugin removes unused fans. After upgrading from the original "checkpoint_fan" check, service discovery should be performed on the affected hosts to remove obsolete services. See github for details. ### Improvements over the original check - Configurable state handling: - Out-of-range conditions can be mapped to the desired Checkmk state (default: `CRIT`) - Sensor reading errors can be mapped to the desired Checkmk state (default: `UNKNOWN`) - Optional performance data - Removed unused fans
