PTF CheckTimeSNMP

With Custom Sensor PTF CheckTimeSNMP you can check the time difference between a device and your PRTG server/probe in seconds.

The sensor gets the time from the device using SNMP and compares it with the local time of your PRTG server/probe.

-s=device [-c=community string] [-v=SNMP version] [-p=SNMP port]

-s=  IP address or DNS name of the device to check.")
-c=  Optional, SNMP community string for SNMP v1/v2c. Default=public.")
-v=  Optional, SNMP version. Supported version: 1 or 2c. Default=1.")
-p=  Optional, SNMP port number on remote host. Default=161")

The Custom Sensor can be downloaded from this page.

There are not plans for native support for this datatype, the reason for this is that this can usually not be directly translated as a numerical value which PRTG can use, meaning there's only a handful of scenarios were this would be useful.

The only alternatives are PRTGToolsFamily script above or creating the custom sensor with NET-SNMP + PRTG yourself. Please note that the output of the script must be an integer or double numerical value, and the output of the script must comply with PRTG's API for custom sensors.

Please check the following NET-SNMP + Powershell Examples:

• Sensor for BGP status
• Problem with a Synology UPS OID

Note: PRTG does not provide parameters for credentials in SNMPV3, in that case hard-code them in the script or define them as parameters in the sensor's settings (without placeholders).

For reference, this is the definition for the TEXTUAL-CONVENTION which defines the DateandTime format as documented in the SNMPv2-TC MIB.

DateAndTime ::= TEXTUAL-CONVENTION

            - the value of year is in network-byte order
            - daylight saving time in New Zealand is +13

            For example, Tuesday May 26, 1992 at 1:30:15 PM EDT would be
            displayed as:

                             1992-5-26,13:30:15.0,-4:0

            Note that if only local time is known, then timezone
            information (fields 8-10) is not present."
