Installation

For general plugin installation instructions see the plugins repo README.md

Release binaries for

• x86_64-linux
• armv7-linux (Raspberry Pi 32bit)
• aarch64-linux (Raspberry Pi 64bit)

can be found on the release page. If you are unsure about your architecture you can run uname -m.

They require glibc>=2.31, which you can check with ldd --version.

Building

You can build the plugin yourself instead of using the release binaries. First clone the repo:

git clone https://github.com/daywalker90/summars.git

Install a recent rust version (rustup is recommended) and in the summars folder run:

cargo build --release

After that the binary will be here: target/release/summars

Note: Release binaries are built using cross and the optimized profile.

Example Usage

There are currently two commands:

• summars the main command
• summars-refreshalias to manually refresh the alias cache

How to set options

summars is a dynamic plugin with dynamic options, so you can start it after CLN is already running and modify it's options after the plugin is started. There are three different methods of setting the options:

1. Running the summars command. This only sets the options temporarily for this one execution of summars and there are some exceptions for options that don't make sense here.

• Example: lightning-cli summars summars-forwards=6

2. When starting the plugin dynamically.

• Example: lightning-cli -k plugin subcommand=start plugin=/path/to/summars summars-forwards=6

3. Permanently saving them in the CLN config file. ⚠️If you want to do this while CLN is running you must use setconfig instead of manually editing your config file! ⚠️If you have options in the config file (either by manually editing it or by using the setconfig command) make sure the plugin will start automatically with CLN (include plugin=/path/to/summars or have a symlink to summars in your plugins folder). This is because CLN will refuse to start with config options that don't have a corresponding plugin loaded. ⚠️If you edit your config file manually while CLN is running and a line changes their line number CLN will crash when you use the setconfig command, so better stick to setconfig only during CLN's uptime!

• Example: lightning-cli setconfig summars-forwards 6

You can mix these methods and if you set the same option with different methods, it will pick the value from your most recently used method.

Options

Channels table

• summars-columns Comma-separated list of enabled columns in the channel table. Also dictates order of columns. Valid columns: GRAPH_SATS, PERC_US, OUT_SATS, IN_SATS, TOTAL_SATS, SCID, MIN_HTLC, MAX_HTLC, FLAG, BASE, IN_BASE, PPM, IN_PPM, ALIAS, PEER_ID, UPTIME, HTLCS, STATE. Default columns: OUT_SATS, IN_SATS, SCID, MAX_HTLC, FLAG, BASE, PPM, ALIAS, PEER_ID, UPTIME, HTLCS, STATE
• summars-sort-by Sort by column name. Use - before column name to reverse sort. Valid columns are all summars-columns except for GRAPH_SATS. Default is SCID
• summars-exclude-states List if excluded channel states. Comma-separated. Valid states are: OPENING, AWAIT_LOCK, OK, SHUTTING_DOWN, CLOSINGD_SIGEX, CLOSINGD_DONE, AWAIT_UNILATERAL, FUNDING_SPEND, ONCHAIN, DUAL_OPEN, DUAL_COMITTED, DUAL_COMMIT_RDY, DUAL_AWAIT, AWAIT_SPLICE and PUBLIC, PRIVATE to filter channels by their network visibility, aswell as or ONLINE,OFFLINE to filter by connection status.

Forwards table

• summars-forwards List successfull forwards of the last x hours. Default is 0 hours (disabled)
• summars-forwards-limit Additionally limit the amount of entries shown by summars-forwards. Default is 0 (off)
• summars-forwards-columns Comma-separated list of enabled columns in the forwards table. Also dictates order of columns. Valid columns: received_time, resolved_time, in_channel, out_channel, in_sats, in_msats, out_sats, out_msats, fee_sats, fee_msats, eff_fee_ppm. Default columns: resolved_time, in_channel, out_channel, in_sats, out_sats, fee_msats
• summars-forwards-filter-amount-msat Filter forwards where in amount is smaller than or equal to x msat and show a summary of those forwards instead. Default is -1 (disabled)
• summars-forwards-filter-fee-msat Filter forwards where fee amount is smaller than or equal to x msat and show a summary of those forwards instead. Default is -1 (disabled)
• summars-forwards-alias In the forwards list show aliases insted of scid's. Default is true

Pays table

• summars-pays List successfull payments of the last x hours. Default is 0 hours (disabled)
• summars-pays-limit Additionally limit the amount of entries shown by summars-pays. Default is 0 (off)
• summars-pays-columns Comma-separated list of enabled columns in the pays table. Also dictates order of columns. Valid columns: completed_at, payment_hash, sats_requested, msats_requested, sats_sent, msats_sent, fee_sats, fee_msats, destination, description, preimage. Default columns are: completed_at, payment_hash, sats_sent, fee_sats, destination⚠️ If you enable the description field in most cases an extra RPC call is necessary for each displayed payment. This could slow down the response time of summars if you have alot of payments in your configured time window.

Invoices table

• summars-invoices List successfully paid invoices of the last x hours. Default is 0 hours (disabled)
• summars-invoices-limit Additionally limit the amount of entries shown by summars-invoices. Default is 0 (off)
• summars-invoices-columns Comma-separated list of enabled columns in the invoices table. Also dictates order of columns. Valid columns: paid_at, label, description, sats_received, msats_received, payment_hash, preimage. Default columns are: paid_at, label, sats_received, payment_hash
• summars-invoices-filter-amount-msat Filter invoices where received amount is smaller than or equal to x msat and show a summary of those invoices instead. Default is -1 (disabled)

Background tasks

• summars-refresh-alias How many hours between refreshing the node aliases in memory. Default is 24 hours
• summars-availability-interval How often the availability should be calculated. Default is 300 seconds
• summars-availability-window How many hours the availability should be averaged over. Default is 72 hours

Formatting

• summars-locale Set locale for number and date formatting. Default is the systems locale with en-US as fallback, if it could not be detected.
• summars-utf8 Switch on/off special characters in node aliases. Off replaces special characters with a ?. Default is true (on)
• summars-style Set the table style for the summary table. Valid values are: ascii, modern, sharp, rounded, extended, psql, markdown, re_structured_text, dots, ascii_rounded, blank, empty. You can see previews here: tabled-styles. Default is modern
• summars-flow-style Same as summars-style but for the "flow" tables (forwards/pays/invoices). Default is blank
• summars-max-alias-length How long aliases are allowed to be before they get cut off. If you use a negative value (e.g. -20) it will use wrapping at that length instead. Default is 20
• summars-max-description-length How long descriptions are allowed to be before they get cut off. If you use a negative value (e.g. -30) it will use wrapping at that length instead. Default is 30
• summars-max-label-length How long invoice labels are allowed to be before they get cut off. If you use a negative value (e.g. -30) it will use wrapping at that length instead. Default is 30

Misc

• summars-json Set output to json format. Default is false

Availability Database

The availability is persistent through plugin restarts. The db is located in your lightning folder in the summars folder (e.g. .lightning/bitcoin/summars/availdb.json). If you want to reset these stats stop the plugin and then remove the file.

Thanks

Thank you to cdecker for helping me get into writing a plugin with cln-plugin, the people in https://t.me/lightningd and the authors of the original summary plugin.
