Print latest packet sequences in log or app.yaml

[orkunkl]

Helpful when debugging and tracking current status of relayer

[bartmacbartek]

There's last-queried-heights.json file at $HOME/.ibc-setup directory (by default):

type LastQueriedHeights = {
  packetHeightA: number,
  packetHeightB: number,
  ackHeightA: number,
  ackHeightB: number
}

Is it any helpful? If not, could you elaborate a bit more on what you would like to see in logs, please?

[orkunkl]

Not exactly, LastQueriedHeights is actually shown in the logs while the relayer is running, but packet height and ack height indicates the latest heights a packet sent and acknowledged.
Packets has a sequence identifier inside that is sequential and would be helpful to see this in the logs.

interface Packet {
  sequence: uint64
  timeoutHeight: Height
  timeoutTimestamp: uint64
  sourcePort: Identifier
  sourceChannel: Identifier
  destPort: Identifier
  destChannel: Identifier
  data: bytes
}

I cannot add it as info level, as we print one line for all packets:

Relay ${packets.length} packets from ${this.chain(source)} => ${this.otherChain(source)}

We do show it in verbose mode where we show the data of each packet:

Sending packet #${packet.sequence.toNumber()} from ${this.chainId}:${packet.sourceChannel}, presentPacketData(packet.data)

This contains the channel and sequence along with the full packet application data (eg. ics20 source/receive/denom/amount).

You can just run with -v to get this info. Or is there some more info you need?

It has been some time since I created this request. I should have explained the issue better in the description. If packet height provided using verbose mode, all fine.
