<# .SYNOPSIS Checks availability, state and utilization of the physical hard disk .DESCRIPTION Checks the state, accessibility and usage of a physical disk. There are a total of 8 PerfCounter checks that represent the usage of a physical disk, and each of them has its own threshold value, i.e. you cannot use only one threshold value to check how fast a disk is writing and reading. .PARAMETER IncludeDisk Specify the index id of disks you want to include for checks. Example 0, 1 .PARAMETER ExcludeDisk Specify the index id of disks you want to exclude from checks. Example 0, 1 .PARAMETER IncludePartition Specify the partition drive letters for disks to include for checks. Example C:, D: .PARAMETER ExcludePartition Specify the partition drive letters for disks to exclude from checks. Example C:, D: .PARAMETER DiskReadSecWarning Warning threshold for disk Reads/sec is the rate of read operations on the disk. .PARAMETER DiskReadSecCritical Critical treshold for disk Reads/sec is the rate of read operations on the disk. .PARAMETER DiskWriteSecWarning Warning theeshold for disk Writes/sec is the rate of write operations on the disk. .PARAMETER DiskWriteSecCritical Critical threshold for disk Writes/sec is the rate of write operations on the disk. .PARAMETER DiskQueueLenWarning Warning threshold for current Disk Queue Length is the number of requests outstanding on the disk at the time the performance data is collected. It also includes requests in service at the time of the collection. This is a instantaneous snapshot, not an average over the time interval. Multi-spindle disk devices can have multiple requests that are active at one time, but other concurrent requests are awaiting service. This counter might reflect a transitory high or low queue length, but if there is a sustained load on the disk drive, it is likely that this will be consistently high. Requests experience delays proportional to the length of this queue minus the number of spindles on the disks. For good performance, this difference should average less than two. .PARAMETER DiskQueueLenCritical Critical threshold for current Disk Queue Length is the number of requests outstanding on the disk at the time the performance data is collected. It also includes requests in service at the time of the collection. This is a instantaneous snapshot, not an average over the time interval. Multi-spindle disk devices can have multiple requests that are active at one time, but other concurrent requests are awaiting service. This counter might reflect a transitory high or low queue length, but if there is a sustained load on the disk drive, it is likely that this will be consistently high. Requests experience delays proportional to the length of this queue minus the number of spindles on the disks. For good performance, this difference should average less than two. .PARAMETER DiskReadByteSecWarning Warning threshold for disk Read Bytes/sec is the rate at which bytes are transferred from the disk during read operations. .PARAMETER DiskReadByteSecCritical Critical threshold for disk Read Bytes/sec is the rate at which bytes are transferred from the disk during read operations. .PARAMETER DiskWriteByteSecWarning Warning threshold for disk Write Bytes/sec is rate at which bytes are transferred to the disk during write operations. .PARAMETER DiskWriteByteSecCritical Critical threshold for disk Write Bytes/sec is rate at which bytes are transferred to the disk during write operations. .PARAMETER DiskAvgTransSecWarning Warning threshold for avg. Disk sec/Transfer is the time, in seconds, of the average disk transfer. If the threshold values are not in seconds, please enter a unit such as (ms, s, m, h, ...) .PARAMETER DiskAvgTransSecCritical Critical threshold for avg. Disk sec/Transfer is the time, in seconds, of the average disk transfer. If the threshold values are not in seconds, please enter a unit such as (ms, s, m, h, ...) .PARAMETER DiskAvgReadSecWarning Warning threshold for avg. Disk sec/Read is the average time, in seconds, of a read of data from the disk. If the threshold values are not in seconds, please enter a unit such as (ms, s, m, h, ...) .PARAMETER DiskAvgReadSecCritical Critical threshold for avg. Disk sec/Read is the average time, in seconds, of a read of data from the disk. If the threshold values are not in seconds, please enter a unit such as (ms, s, m, h, ...) .PARAMETER DiskAvgWriteSecWarning Warning threshold for Avg. Disk sec/Write is the average time, in seconds, of a write of data to the disk. If the threshold values are not in seconds, please enter a unit such as (ms, s, m, h, ...) .PARAMETER DiskAvgWriteSecCritical Critical threshold for Avg. Disk sec/Write is the average time, in seconds, of a write of data to the disk. If the threshold values are not in seconds, please enter a unit such as (ms, s, m, h, ...) .PARAMETER CheckLogicalOnly Set this to include only disks that have drive letters like C:, D:, ..., assigned to them. Can be combined with include/exclude filters .EXAMPLE PS> Invoke-IcingaCheckDiskHealth -DiskReadSecWarning 0 -DiskReadSecCritical 1 -DiskAvgTransSecWarning 5s -DiskAvgTransSecCritical 10s -DiskReadByteSecWarning 3000 -DiskReadByteSecCritical 5000 -Verbosity 2 [CRITICAL] Check package "Physical Disk Package" (Match All) - [CRITICAL] _Total disk read bytes/sec \_ [CRITICAL] Check package "Disk #_Total" (Match All) \_ [OK] _Total avg. disk sec/read: 0s \_ [OK] _Total avg. disk sec/transfer: 0s \_ [OK] _Total avg. disk sec/write: 0s \_ [OK] _Total current disk queue length: 0 \_ [CRITICAL] _Total disk read bytes/sec: Value "808675.12B" is greater than threshold "5000B" \_ [OK] _Total disk reads/sec: 0 \_ [OK] _Total disk write bytes/sec: 6679.13B \_ [OK] _Total disk writes/sec: 1.68 \_ [OK] Check package "Disk #0" (Match All) \_ [OK] F: C: avg. disk sec/read: 0s \_ [OK] F: C: avg. disk sec/transfer: 0s \_ [OK] F: C: avg. disk sec/write: 0s \_ [OK] F: C: current disk queue length: 0 \_ [OK] F: C: disk read bytes/sec: 0B \_ [OK] F: C: disk reads/sec: 0 \_ [OK] F: C: disk write bytes/sec: 6680.76B \_ [OK] F: C: disk writes/sec: 1.64 \_ [OK] F: C: Is Offline: False \_ [OK] F: C: Is ReadOnly: False \_ [OK] F: C: Operational Status: OK \_ [OK] F: C: Status: OK | 'f_c_avg_disk_sectransfer'=0s;5;10 'f_c_disk_write_bytessec'=6680.76B;;
