Command Line Parameters
perfquery /n:<count> /l /m <query path | oid>
<query path> |
Performance counter to read, e.g. "Processor(_Total)\% Processor Time" |
/n:<count> |
Repeat query <count> times |
/l |
Loop indefinitely |
/i:<seconds> |
When looping, sleep <milliseconds> between iterations, default is 500ms |
/m |
Minimal output, only show counter value |
/s |
Query SNMP instead of a local performance counter |
/f |
Display values as floating point (windows performance counters only) |
/host:<remote host> |
Host name to send SNMP GET request to |
/instance:<instance> |
When returning table data through SNMP, specify the OID which describes each instance |
/u:<community | user> |
SNMP v1/v2c community name or SNMP v3 user name |
/a:<MD5 or SHA> |
SNMP v3 authentication algorithm |
/passauth:<password> |
SNMP v3 authentication password |
/c:<DES | 3DES | AES> |
SNMP v3 encryption algorithm |
/passcrypto:<password> |
SNMP v3 encryption password |
Examples
Example 1: Query performance counter "Processor(_Total)\% Processor Time" 5 times with regular output:
perfquery.exe "Processor(_Total)\% Processor Time" /n:5
Processor(_Total)\% Processor Time: [_Total] now=8, min=0, max=8, avg=7.61
Processor(_Total)\% Processor Time: [_Total] now=1, min=1, max=1, avg=4.45
Processor(_Total)\% Processor Time: [_Total] now=1, min=1, max=1, avg=3.46
Processor(_Total)\% Processor Time: [_Total] now=8, min=1, max=8, avg=4.61
Processor(_Total)\% Processor Time: [_Total] now=1, min=1, max=8, avg=3.95
Summary
=======
Iterations: 5
Duration: 3 seconds
Processor(_Total)\% Processor Time: [_Total] min=1, max=8, avg=3.95
Example 2: Query CPU usage from SNMP host 192.168.10.1 with SNMP community "secret" 5 times, wait 250ms between each query
perfquery.exe /s /host:192.168.10.1 /u:secret "1.3.6.1.4.1.2021.11.9.0+1.3.6.1.4.1.2021.11.10.0" /n:5 /i:250
1.3.6.1.4.1.2021.11.9.0+1.3.6.1.4.1.2021.11.10.0: now=1, min=0, max=1, avg=1.00
1.3.6.1.4.1.2021.11.9.0+1.3.6.1.4.1.2021.11.10.0: now=0, min=0, max=0, avg=0.67
1.3.6.1.4.1.2021.11.9.0+1.3.6.1.4.1.2021.11.10.0: now=0, min=0, max=0, avg=0.50
1.3.6.1.4.1.2021.11.9.0+1.3.6.1.4.1.2021.11.10.0: now=0, min=0, max=0, avg=0.40
1.3.6.1.4.1.2021.11.9.0+1.3.6.1.4.1.2021.11.10.0: now=0, min=0, max=0, avg=0.33
