This example shows the events in Snare format. The first four fields are the event header and may be formatted differently in other event formats.

1. Formats

The following formats are possible formats for telemetry events:

...

<Hostname>    TelemetryLog    <SeverityLevel>   <TimeCreated> <TimeCreated(YYYY-MM-DD HH:MM)>   <MetricType> <InstanceName> <EventName>  <Value>  EventChecksum=<EventChecksum>

SNARE V2

<Hostname>    TelemetryLog    <SeverityLevel>    {"Event":{"Data":{"MetricType":"<MetricType>","InstanceName":"<InstanceName>","EventName":"<EventName>","Value":"<Value>"},"System":{"TimeCreated":{"SystemTime":"

...

<SystemTime(YYYY-MM-DDTHH:MM.ssssssZ)>","LocalTime":"

...

<LocalTime(YYYY-MM-DDThh:mm:ss.ssssss±hh:mm)>"}}}} 

SYSLOG (RFC3164)

<<S>><TimeCreated (MMM DD HH:MM:SS)> <Hostname> TelemetryLog <SeverityLevel> <TimeCreated> <TimeCreated(YYYY-MM-DD HH:MM)> <MetricType> <InstanceName> <EventName> <Value> EventChecksum=<EventChecksum>

SYSLOG Alt (RFC5424 Compatible)

<<S>><TimeCreated (MMM DD HH:MM:SS)> <Hostname> TelemetryLog[<SeverityLevel>]:<TimeCreated>:<TimeCreated(YYYY-MM-DD HH:MM)> <MetricType> <InstanceName> <EventName> <Value> EventChecksum=<EventChecksum>

SYSLOG (RFC5424)

<<S>><SyslogVersion> <Time Created <TimeCreated(YYYY-MM-DDThh:mm:ss.ssssss±hh:mm)> <Hostname> <ProductName> - TelemetryLog - <SeverityLevel> <TimeCreated> <TimeCreated(YYYY-MM-DD HH:MM)> <MetricType> <InstanceName> <EventName> <Value> EventChecksum=<EventChecksum>

2. Telemetry Event Fields

Below is a table describing the contents of a Telemetry Event generated by Snare Agent. 

FieldTypeDescription
HostnameStringThe host name of the originating computer.
EventTypeStringTelemetryLog - the type of event generated.

SeverityLevel

IntegerThe severity level (Criticality) of the generated event.
TimeCreatedDatetimeThe time at which the telemetry event was . (YYYY-MM-DDT hh:mm:ss)created. The format of the time depends on the log format that is selected.
MetricTypeStringThis is the hardware component source of the event; Events from the CPU, Disk, Memory or Network can be collected and are labelled as CPU, DSK, MEM or NET respectively.

InstanceName(May change to ObjectName)

StringThe name of the hardware interface the event is sourced. For example, if events from the Disk (DSK) are collected, there may be multiple storage interfaces present such as  HarddiskVolume1, HarddiskVolume2, etc.
EventNameStringThe name of the metric of the hardware interface. Given a hardware interface named by it's InstanceName, the EventName denotes the metric of the interface that is collected. Eg, EventName: ' % Free Space' from InstanceName:'HarddiskVolume1'
ValueFloatThe value of the metric.
EventChecksum (Optional)StringThe calculated digest (checksum) valueSHA3-512 hash of the event excluding the EventChecksum field; this is additional optional data that may be set in the
EventSourceId (Optional)StringConfigurable ID/string for identifying the agent/host. This is also optional data like the EventChecksum and is selected likewise.


Please refer to The Web User Interface (UI) Log Sources → Telemetry page in this User Guide for instructions on how to configure periodic Telemetry scans in the Snare Agent.
