A new version of check_esxi_hardware, an open source monitoring plugin to monitor the hardware of VMware ESXi servers, is available.

The new version (20220708) adds the possibility to use a different output format, by adding a new parameter --format. This parameter currently allows either "string" or "json" as value.

Without setting the --format parameter, the default plugin output is a string:

$ ./check_esxi_hardware.py -H myesxi -U root -P "secret" -V hp
OK - Server: Cisco Systems Inc UCSC-C220-M5SX s/n: WZPXXXXXXXX Chassis S/N: WZPXXXXXXXX  System BIOS: C220M5.4.0.4r.0.0218212214 2021-02-18

By using --format json, the plugin's output shows up as JSON:

$ ./check_esxi_hardware.py -H myesxi -U root -P "secret" -V hp --format json
{"Bios Info": "System BIOS: C220M5.4.0.4r.0.0218212214 2021-02-18", "ChassisSerialNumber": "WZPXXXXXXXX", "GlobalStatus": 0, "SerialNumber": "WZPXXXXXXXX"}

With the additional --pretty parameter, the JSON output can be made more human readable:

$ ./check_esxi_hardware.py -H myesxi -U root -P "secret" -V hp --format json --pretty
{
    "Bios Info": "System BIOS: C220M5.4.0.4r.0.0218212214 2021-02-18",
    "ChassisSerialNumber": "WZPXXXXXXXX",
    "GlobalStatus": 0,
    "SerialNumber": "WZPXXXXXXXX"
}

The JSON output is needed if you use Zabbix as your monitoring software. Documentation of check_esxi_hardware has been updated.
