Seq Documentation and Support

Welcome to the Seq documentation hub. You'll find comprehensive guides and documentation to help you start working with Seq as quickly as possible, as well as support if you get stuck. Let's jump right in!

Get Started    

Command-line Client

The Seq command-line client supports logging (seqcli log), searching (search), tailing (tail), querying (query) and JSON or plain-text log file ingestion (ingest), as well as a number of administration tasks.

Getting started

Install or unzip the release for your operating system.

To set a default server URL, run:

seqcli config -k connection.serverUrl -v https://your-seq-server

The API key will be stored in your SeqCli.json configuration file; on Windows, this is encrypted using DPAPI; on Mac/Linux the key is currently stored in plain text. As an alternative to storing the API key in configuration, it can be passed to each command via the --apikey= argument.

seqcli is also available as a Docker container under datalust/seqcli:

docker run --rm datalust/seqcli:latest <command> [<args>]

Use Docker networks and volumes to make local files and other containers accessible to seqcli within its container.

Commands

Usage:

seqcli <command> [<args>]

Available commands:

  • apikey
  • app
    • app define — Generate an app definition for a .NET [SeqApp] plug-in.

Extraction patterns

The seqcli ingest command can be used for parsing plain text logs into structured log events.

seqcli ingest -x "{@t:timestamp} [{@l:level}] {@m:*}{:n}{@x:*}"

The -x argument above is an extraction pattern that will parse events like:

2018-02-21 13:29:00.123 +10:00 [ERR] The operation failed
System.DivideByZeroException: Attempt to divide by zero
  at SomeClass.SomeMethod()

Syntax

Extraction patterns have a simple high-level syntax:

  • Text that appears in the pattern is matched literally - so a pattern like Hello, world! will match logging statements that are made up of this greeting only,
  • Text between {curly braces} is a match expression that identifies a part of the event to be extracted, and
  • Literal curly braces are escaped by doubling, so {{ will match the literal text {, and }} matches }.

Match expressions have the form:

{name:matcher}

Both the name and matcher are optional, but either one or the other must be specified. Hence {@t:timestamp} specifies a name of @t and value timestamp, {IPAddress} specifies a name only, and {:n} a value only (in this case the built-in newline matcher).

The name is the property name to be extracted; there are four built-in property names that get special handling:

  • @t - the event's timestamp
  • @m - the textual message associated with the event
  • @l - the event's level
  • @x - the exception or backtrace associated with the event

Other property names are attached to the event payload, so {Elapsed:dec} will extract a property called Elapsed, using the dec decimal matcher.

Match expressions with no name are consumed from the input, but are not added to the event payload.

Matchers

Matchers identify chunks of the input event.

Different matchers are needed so that a piece of text like 200OK can be separated into separate properties, i.e. {StatusCode:nat}{Status:alpha}. Here, the nat (natural number) matcher also coerces the result into a numeric value, so that it is attached to the event payload numerically as 200 instead of as the text "200".

There are three kinds of matchers:

  • Matchers like alpha and nat are built-in named matchers.
  • The special matchers *, ** and so-on, are non-greedy content matchers; these will match any text up until the next pattern element matches (*), the next two elements match, and so-on. We saw this in action with the {@m:*}{:n} elements in the example - the message is all of the text up until the next newline.
  • More complex compound matchers are described using a sub-expression. These are prefixed with an equals sign =, like {Phone:={:nat}-{:nat}-{:nat}}. This will extract chunks of text like 123-456-7890 into the Phone property.

Processing

Extraction patterns are processed from left to right. When the first non-matching pattern is encountered, extraction stops; any remaining text that couldn't be matched will be attached to the resulting event in an @unmatched property.

Multi-line events are handled by looking for lines that start with the first element of the extraction pattern to be used. This works well if the first line of each event begins with something unambiguous like an iso8601dt timestamp; if the lines begin with less specific syntax, the first few elements of the extraction pattern might be grouped to identify the start of events more accurately:

{:=[{@t} {@l}]} {@m:*}

Here the literal text [, a timestamp token, adjacent space , level and closing ] are all grouped so that they constitute a single logical pattern element to identify the start of events.

When logs are streamed into seqcli ingest in real time, a 10 ms deadline is applied, within which any trailing lines that make up the event must be received.

Examples

Tail systemd logs

journalctl -f -n 0 |
  seqcli ingest -x "{@t:syslogdt} {host} {ident:*}: {@m:*}{:n}" --invalid-data=ignore

Tail /var/log/syslog

tail -c 0 -F /var/log/syslog |
  seqcli ingest -x "{@t:syslogdt} {host} {ident:*}: {@m:*}{:n}"

Ingest an IIS/W3C web server log

This example ingests log files in the format:

#Fields: date time s-ip cs-method cs-uri-stem cs-uri-query s-port cs-username c-ip cs(User-Agent) 
cs(Referer) sc-status sc-substatus sc-win32-status sc-bytes cs-bytes time-taken

The extraction pattern is wrapped in the example for display purposes, and must appear all in one string argument when invoked.

seqcli ingest -i http.log --invalid-data=ignore -x "{@t:w3cdt} {ServerIP} {@m:={Method} {RequestPath}} 
{Query} {Port:nat} {Username} {ClientIP} {UserAgent} {Referer} {StatusCode:nat} {Substatus:nat} 
{Win32Status:nat} {ResponseBytes:nat} {RequestBytes:nat} {Elapsed}{:n}"

A nested {@m:= pattern is used to collect a substring of the log line for display as the event's message.
