# Monza

# WIP area: this repo is just a fork!
|
||||
|
||||
Find notifications in [Neo3](https://neo.org/) compatible chains and more.
|
||||
|
||||
## Features
|
||||
|
||||
- Stores chain blocks in the filesystem, so it will not fetch it again
|
||||
at restart
|
||||
- Works with multiple chains by storing chain blocks based on magic number
|
||||
- Detailed notification output for NEP and FrostFS notifications
|
||||
- Use relative numbers for search interval
|
||||
- Use nice names for native contracts
|
||||
- Search multiple notifications at once
|
||||
|
||||
## Examples
|
||||
|
||||
```
|
||||
$ monza run -r http://localhost:30333 --from 22 --to 24 -n NewEpoch:* -n Transfer:gas

|
||||
|
||||
### Detailed output
|
||||
|
||||
- NEP-17 `Transfer`
|
||||
|
||||
```
|
||||
block:23 at:2023-09-27T13:50:04+03:00 name:Transfer from:6a131b2be19b7618dc22dbc8147015d947af67ce to:c1e14f19c3e60d0b9244d06dd7ba9b113135ec3b amount:243839460
|
||||
```
|
||||
|
||||
- FrostFS `NewEpoch`
|
||||
|
||||
```
|
||||
block:22 at:2023-09-27T13:50:03+03:00 name:NewEpoch epoch:1
|
||||
```
|
||||
|
||||
- FrostFS `AddPeerSuccess`
|
||||
|
||||
```
|
||||
block:21 at:2023-09-27T13:50:02+03:00 name:AddPeerSuccess pubkey:[..6a8131]
|
||||
```
|
||||
|
||||
### Notifications
|
||||
|
||||
Search notifications based on notification name and contract address.
|
||||
|
||||
```
|
||||
monza run -r [endpoint] --from 110000 --to 110100 -n NewEpoch:ab8a83432af3cd32ce6ba3797f62b1ba330d7c3d
|
||||
```
|
||||
|
||||
Use wildcard to search notifications from any contract.
|
||||
|
||||
```
|
||||
monza run -r [endpoint] --from 110000 --to 110100 -n NewEpoch:*
|
||||
```
|
||||
|
||||
Use native contract names such as `gas` and `neo`.
|
||||
|
||||
```
|
||||
monza run -r [endpoint] --from 110000 --to 110100 -n Transfer:gas
|
||||
```
|
||||
|
||||
Search for multiple notifications.
|
||||
|
||||
```
|
||||
monza run -r [endpoint] --from 110000 --to 110100 -n Transfer:gas -n NewEpoch:*
|
||||
```
|
||||
|
||||
### Intervals
|
||||
|
||||
Define start and stop blocks.
|
||||
|
||||
```
|
||||
monza run -r [endpoint] --from 110000 --to 110100 -n NewEpoch:*
|
||||
```
|
||||
|
||||
Omit `--to` flag to search up to the latest block.
|
||||
|
||||
```
|
||||
monza run -r [endpoint] --from 110000 -n NewEpoch:*
|
||||
```
|
||||
|
||||
To look for `100` blocks before the latest block use prefix `m` (minus)
|
||||
|
||||
```
|
||||
monza run -r [endpoint] --from m100 -n NewEpoch:*
|
||||
```
|
||||
|
||||
To look for `100` blocks after specified `from` block, use prefix `p` (plus)
|
||||
|
||||
```
|
||||
monza run -r [endpoint] --from 101230 --to p100 -n NewEpoch:*
|
||||
```
|
||||
|
||||
### Other
|
||||
|
||||
Blocks are stored in bolt databases. Specify database dir with `-c` flag
|
||||
(default path is `$HOME/.config/monza`)
|
||||
|
||||
```
|
||||
monza run -r [endpoint] -c ./cache --from 110000 --to 110100 -n NewEpoch:*
|
||||
```
|
||||
|
||||
To speed up block fetching from the RPC node, use more parallel workers with
|
||||
`-w` flag.
|
||||
|
||||
```
|
||||
monza run -r [endpoint] -w 100 --from 110000 --to 110100 -n NewEpoch:*
|
||||
```
|
||||
|
||||
To disable progress bar use `--disable-progress-bar` flag.
|
||||
|
||||
### Stutter
|
||||
|
||||
Stutter command searches for blocks that produced with threshold a delay
|
||||
or slower.
|
||||
|
||||
```
|
||||
$ monza stutter -r [endpoint] --from 1159200 --to p30 --threshold 20s
|
||||

|
||||
block:1159223 at:2022-03-29T18:31:13+03:00 [<- stutter for 1m30s]
|
||||
```
|
||||
|
||||
### Explorer
|
||||
|
||||
Run monza in interactive mode to navigate through blocks, transactions and
|
||||
notifications with `explore` command.
|
||||
|
||||
```
|
||||
$ monza explore -r [endpoint]
|
||||
```
|
||||
|
||||
## Build
|
||||
|
||||
Use `make build` command. Binary will be stored in `./bin/monza`.
|
||||
|
||||
## To Do
|
||||
|
||||
- [ ] `monza cache` command to manage bbolt instances: provide size and option to delete
|
||||
- [ ] Add verbose flag with for detailed view of notification body
|
||||
- [ ] Add more native contract hashes aliases
|
||||
- [ ] More NEP support (NEP-11?)
