Logparse is a shell script that parses Caddy's JSON log files and outputs them as formatted text. It supports the Common Log Format and Combined Log Format, usually used by traditional HTTP servers like Apache, however it is easy to customise the output using the --selector option or by using a config file. Logparse uses the powerful jq tool to process the JSON logs.

JSON, or JavaScript Object Notation, is a lightweight data interchange format that is easy for humans to read and write, and easy for machines to parse and generate. JSON is built on two structures: a collection of name/value pairs (often realised as an object or dictionary) and an ordered list of values (often realised as an array). Its simplicity and compatibility with most programming languages make it an ideal choice for configuration files, data storage, and transmission of data between a server and a client.

Caddy is a HTTP-1-2-3 server is a secure and powerful web server that uses JSON extensively, providing structured and easily parseable data. This makes it straightforward to analyse server logs programmatically, allowing for detailed monitoring and troubleshooting. By using JSON, Caddy ensures that log entries are consistent and comprehensive, enabling administrators to leverage tools like jq for querying logs, or integrate with other monitoring solutions that support JSON.

While JSON is excellent for machine parsing, it can be cumbersome when you need to quickly parse trough log files using shell tools like grep, less or tail. The huge volume of data makes it hard to get a quick overview. I wrote logparse specifically to make it easier for me to read Caddy's JSON log files, though it should be easy to adapt the configuration for other JSON files.

Common Log Format[edit | edit source]

Traditional HTTP/web servers like Apache usually use plain text files to store access logs or error logs. A typical access_log file consists of one line per access, containing a number of predefined fields. Most servers supports extensive customisation of what fields that are included, but to make it easier for external tools to parse and analyse the logs, two standards exists, the Common Log Format (CLF) and the Combined Log Format. The Apache website https://httpd.apache.org/docs/2.4/logs.html has detailed information on these formats.

In the Common Log Format, the fields are Client IP User ID [datetime] "Method URI Protocol" Status code Size 

Common Log Format
192.168.0.122 - [2024-05-26 09:38:04] "GET /img/favicon.webp HTTP/3.0" 200 6866

In the Combined Log Format, the fields are: Client IP User ID [datetime] "Method URI Protocol" Status code Size "Referer" "User agent" 

Combined Log Format
192.168.0.122 - [2024-05-26 09:38:04] "GET /img/favicon.webp HTTP/3.0" 200 6866 "https://mirrors.tnonline.net/img/" "Mozilla/5.0 (X11; Linux x86_64; rv:125.0) Gecko/20100101 Firefox/125.0"

JSON Logs[edit | edit source]

The Caddy JSON log file contains a lot more information, which can be crucial when gathering statistics, analysing issues, etc. Each line represents a complete JSON object with both the request headers and the response headers, as well as error messages and other information. 

Caddy JSON format
{"level":"info","ts":1716716284.7144635,"logger":"http.log.access.log16","msg":"handled request","request":{"remote_ip":"192.168.0.122","remote_port":"40159","client_ip":"192.168.0.122","proto":"HTTP/3.0","method":"GET","host":"mirrors.tnonline.net","uri":"/img/favicon.webp","headers":{"Upgrade-Insecure-Requests":["1"],"Sec-Fetch-Dest":["document"],"Sec-Fetch-User":["?1"],"Accept-Language":["en-GB,en;q=0.5"],"Accept-Encoding":["gzip, deflate, br"],"Alt-Used":["mirrors.tnonline.net"],"Sec-Fetch-Site":["same-origin"],"User-Agent":["Mozilla/5.0 (X11; Linux x86_64; rv:125.0) Gecko/20100101 Firefox/125.0"],"Referer":["https://mirrors.tnonline.net/img/"],"Sec-Fetch-Mode":["navigate"],"Accept":["text/html,application/xhtml+xml,application/xml;q=0.9,image/avif,image/webp,*/*;q=0.8"]},"tls":{"resumed":false,"version":772,"cipher_suite":4865,"proto":"h3","server_name":"mirrors.tnonline.net"}},"bytes_read":0,"user_id":"","duration":0.003348583,"size":6866,"status":200,"resp_headers":{"Date":["Sun, 26 May 2024 09:38:04 GMT"],"Strict-Transport-Security":["max-age=31968001; preload"],"X-Content-Type-Options":["nosniff"],"Last-Modified":["Wed, 19 Dec 2018 23:21:02 GMT"],"Accept-Ranges":["bytes"],"X-Frame-Options":["DENY"],"Cache-Control":["max-age=2592000, public"],"Content-Length":["6866"],"Content-Security-Policy":["default-src 'self'"],"Etag":["\"bqn9jjvvsuvq5aq\""],"Permissions-Policy":["none"],"Vary":["Accept-Encoding"],"Content-Type":["image/webp"],"Server":["Caddy"],"Referrer-Policy":["same-origin"]}}

If we "prettify" it using the jq tool, it looks a lot better. However, we now have 109 lines of code for each log entry!

Usage[edit | edit source]

Common Log Format[edit | edit source]

Logparse uses the CLF as default option if no other options are used. 

# logparse caddy.log
10.10.10.117 - [2024-05-26 11:42:52] "GET /gentoo/gentoo-distfiles/distfiles/9b/tl-hrlatex.source-2021.tar.xz HTTP/2.0" 200 3768

Using custom selectors[edit | edit source]

With the --selector option, it is possible to customise the output. The following selectors are available:

Selector Description
ts Unix Epoch timestamp in 0.1 μs resolution.
datetime Timestamp of the log entry in "YYYY-MM-DD HH:MM:SS" format.
datetime_l Localized timestamp of the log entry in "YYYY-MM-DD HH:MM:SS Z" format.

You can combine these selectors and formatting options as you like.

If you wanted to see the IP address, HTTP protocol and if TLS was used in the connection, you can use the datetime_ms,client_ip, tls_version and tls_cipher_suite selectors. 

# logparse -s "datetime_ms _ client_ip _  proto _ tls_version _ tls_cipher_suite" caddy.log
2024-05-26 13:42:52.601 CET 10.10.10.117 HTTP/2.0 null null
2024-05-26 13:43:50.508 CET 10.10.10.134 HTTP/2.0 null null
2024-05-26 13:44:00.654 CET 10.10.10.132 HTTP/2.0 null null
2024-05-26 02:22:43.414 CET 240e:1:1::1234 HTTP/3.0 TLS 1.3 TLS_AES_128_GCM_SHA256

If you wanted to output a CSV file, you could use the semicolon or tab formatting option. 

# logparse -s "ts tab client_ip tab proto tab status tab uri" caddy.log
1716723772.6014807      10.10.10.117    HTTP/2.0        200     /gentoo/gentoo-distfiles/distfiles/9b/tl-hrlatex.source-2021.tar.xz
1716723830.5081363      10.10.10.134    HTTP/2.0        200     /gentoo/gentoo-portage/app-emulation/metadata.xml
1716723840.6541977      10.10.10.132    HTTP/2.0        200     /gentoo/gentoo-distfiles/distfiles/b6/libvirt-python-9.9.0.tar.gz
1716682963.4146512      240e:1:1::1234  HTTP/3.0        200     /res/browse.css

Configuration File[edit | edit source]

The configuration file allows you to change the default output format by setting the use_selectors variable. 

File: logparse.config
use_selectors="datetime_ms tab client_ip tab size tab status tab uri"

Now when you call logparse without other options, the selectors used in the config file are used. 

# logparse -F logparse.config caddy.log
2024-05-26 13:42:52.601 CET     10.10.10.117    3768    200     /gentoo/gentoo-distfiles/distfiles/9b/tl-hrlatex.source-2021.tar.xz
2024-05-26 13:43:50.508 CET     10.10.10.134    446     200     /gentoo/gentoo-portage/app-emulation/metadata.xml
2024-05-26 13:44:00.654 CET     10.10.10.132    246357  200     /gentoo/gentoo-distfiles/distfiles/b6/libvirt-python-9.9.0.tar.gz
2024-05-26 02:22:43.414 CET     240e:1:1::1234  1577    200     /res/browse.css

It is possible to change the JSON mappings used by logparse. This allows for customising logparse to use a different naming scheme, add new formatting characters or change the JSON mapping to match other types of JSON files.

This is the default configuration used by logparse.

It can be tricky to add new mappings, and to help analyse the actual jq filter constructed by logparse, there is a debug mode that can be enabled. Simply set the environment variable DEBUG before calling logparse. 

# DEBUG=1 logparse -F logparse.config caddy.log
jq -r .
	| (     if .request.client_ip == "" then "-"
	else .request.client_ip
	end     ) as $client_ip
	| ( " " ) as $space
	| (     if .user_id == "" then "-"
	else .user_id
	end     ) as $user_id
	| ( " " ) as $space
	| ( "[" ) as $lsqb
	| (     if .ts | strftime("%Y-%m-%d %H:%M:%S") == "" then "-"
	else .ts | strftime("%Y-%m-%d %H:%M:%S")
	end     ) as $datetime
	| ( "]" ) as $rsqb
	| ( " " ) as $space
	| ( "\"" ) as $quote
	| (     if .request.method == "" then "-"
	else .request.method
