Require the [go programming language](https://golang.org/) (version >= 1.13)
**Raspberry Pi users: be aware that Raspbian ships with Go 1.11** ( see
[#30](https://github.com/edouardparis/lntop/issues/30) )
```
git clone https://github.com/edouardparis/lntop.git
cd lntop && go install ./...
```
With Go version >= 1.16, you can use [`go-install`](https://golang.org/ref/mod#go-install)
```
go install github.com/edouardparis/lntop@latest
```
## Config
First time `lntop` is used a config file `.lntop/config.toml` is created
in the user home directory.
Change macaroon path according to your network.
```toml
[logger]
type = "production"
dest = "/root/.lntop/lntop.log"
[network]
name = "lnd"
type = "lnd"
address = "//127.0.0.1:10009"
cert = "/root/.lnd/tls.cert"
macaroon = "/root/.lnd/data/chain/bitcoin/mainnet/admin.macaroon"
macaroon_timeout = 60
max_msg_recv_size = 52428800
conn_timeout = 1000000
pool_capacity = 4
[views]
# views.channels is the view displaying channel list.
[views.channels]
# It is possible to add, remove and order columns of the
# table with the array columns. The available values are:
columns = [

"ALIAS", # alias of the channel node
"GAUGE", # ascii bar with percent local/capacity
"LOCAL", # the local amount of the channel
"CAP", # the total capacity of the channel
"SENT", # the total amount sent
"RECEIVED", # the total amount received
"HTLC", # the number of pending HTLC
"UNSETTLED", # the amount unsettled in the channel
"CFEE", # the commit fee
"LAST UPDATE", # last update of the channel
"PRIVATE", # true if channel is private
"ID", # the id of the channel
# "SCID", # short channel id (BxTxO formatted)
]
[views.transactions]
# It is possible to add, remove and order columns of the
# table with the array columns. The available values are:
columns = [
"DATE", # date of the transaction
"HEIGHT", # block height of the transaction
"CONFIR", # number of confirmations
"AMOUNT", # amount moved by the transaction
"FEE", # fee of the transaction
"ADDRESSES", # number of transaction output addresses
]
[views.routing]

"STATUS", # one of: active, settled, failed, linkfail
"IN_CHANNEL", # channel id of the incomming channel
"IN_ALIAS", # incoming channel node alias
# "IN_SCID", # incoming short channel id (BxTxO)
# "IN_HTLC", # htlc id on incoming channel
# "IN_TIMELOCK", # incoming timelock height
"OUT_CHANNEL", # channel id of the outgoing channel
"OUT_ALIAS", # outgoing channel node alias
# "OUT_SCID", # outgoing short channel id (BxTxO)
# "OUT_HTLC", # htlc id on outgoing channel
# "OUT_TIMELOCK", # outgoing timelock height
"AMOUNT", # routed amount
"FEE", # routing fee
"LAST UPDATE", # last update
"DETAIL", # error description
]
```
## Routing view
Routing view displays screenful of latest routing events. This information
is not persisted in LND so the view always starts empty and is lost once
you exit `lntop`.
The events are in one of four states:
* `active` - HTLC pending
* `settled` - preimage revealed, HTLC removed
* `failed` - payment failed at a downstream node
* `linkfail` - payment failed at this node
## Docker
If you prefer to run `lntop` from a docker container, `cd docker` and follow [`README`](docker/README.md) there.
