STAN

Collect logs and metrics from STAN servers with Elastic Agent.

Version
1.5.0 (View all)
Compatible Kibana version(s)
8.10.2 or higher
Subscription level
Basic

This integration is used to collect logs and metrics from STAN servers. The integration collects metrics from STAN monitoring server APIs.

Compatibility

The STAN package is tested with Stan 0.15.1.

Logs

log

The log dataset collects the STAN logs.

An example event for log looks as following:

    "@timestamp": "2022-01-12T04:11:35.529Z",
    "agent": {

Exported fields

FieldDescriptionType
@timestamp
Event timestamp.
date
client.ip
IP address of the client (IPv4 or IPv6).
ip
client.port
Port of the client.
long
data_stream.dataset
Data stream dataset.
constant_keyword
data_stream.namespace
Data stream namespace.
constant_keyword
data_stream.type
Data stream type.
constant_keyword
ecs.version
ECS version this event conforms to. ecs.version is a required field and must exist in all events. When querying across multiple indices -- which may conform to slightly different ECS versions -- this field lets integrations adjust to the schema version of the events.
keyword
error.message
Error message.
match_only_text
event.created
event.created contains the date/time when the event was first read by an agent, or by your pipeline. This field is distinct from @timestamp in that @timestamp typically contain the time extracted from the original event. In most situations, these two timestamps will be slightly different. The difference can be used to calculate the delay between your source generating an event, and the time when your agent first processed it. This can be used to monitor your agent's or pipeline's ability to keep up with your event source. In case the two timestamps are identical, @timestamp should be used.
date
event.dataset
Event dataset
constant_keyword
event.kind
This is one of four ECS Categorization Fields, and indicates the highest level in the ECS category hierarchy. event.kind gives high-level information about what type of information the event contains, without being specific to the contents of the event. For example, values of this field distinguish alert events from metric events. The value of this field can be used to inform how these kinds of events should be handled. They may warrant different retention, different access control, it may also help understand whether the data coming in at a regular interval or not.
keyword
event.module
Event module
constant_keyword
event.type
This is one of four ECS Categorization Fields, and indicates the third level in the ECS category hierarchy. event.type represents a categorization "sub-bucket" that, when used along with the event.category field values, enables filtering events down to a level appropriate for single visualization. This field is an array. This will allow proper categorization of some events that fall in multiple event types.
keyword
input.type
Type of Filebeat input.
keyword
log.file.path
Full path to the log file this event came from.
keyword
log.level
Original log level of the log event. If the source of the event provides a log level or textual severity, this is the one that goes in log.level. If your source doesn't specify one, you may put your event transport's severity here (e.g. Syslog severity). Some examples are warn, err, i, informational.
keyword
log.offset
Offset of the entry in the log file.
long
message
For log events the message field contains the log message, optimized for viewing in a log viewer. For structured logs without an original message field, other fields can be concatenated to form a human-readable summary of the event. If multiple messages exist, they can be combined into one message.
match_only_text
network.direction
Direction of the network traffic. Recommended values are: * ingress * egress * inbound * outbound * internal * external * unknown When mapping events from a host-based monitoring context, populate this field from the host's point of view, using the values "ingress" or "egress". When mapping events from a network or perimeter-based monitoring context, populate this field from the point of view of the network perimeter, using the values "inbound", "outbound", "internal" or "external". Note that "internal" is not crossing perimeter boundaries, and is meant to describe communication between two hosts within the perimeter. Note also that "external" is meant to describe traffic between two hosts that are external to the perimeter. This could for example be useful for ISPs or VPN service providers.
keyword
process.pid
Process id.
long
related.ip
All of the IPs seen on your event.
ip
stan.log.client.id
The id of the client
integer
stan.log.msg.bytes
Size of the payload in bytes
long
stan.log.msg.error.message
Details about the error occurred
text
stan.log.msg.max_messages
An optional number of messages to wait for before automatically unsubscribing
integer
stan.log.msg.queue_group
The queue group which subscriber will join
text
stan.log.msg.reply_to
The inbox subject on which the publisher is listening for responses
keyword
stan.log.msg.sid
The unique alphanumeric subscription ID of the subject
integer
stan.log.msg.subject
Subject name this message was received on
keyword
stan.log.msg.type
The protocol message type
keyword
tags
List of keywords used to tag each event.
