### etcd-dump-logs
|
||||
|
||||
etcd-dump-logs inspects etcd db files.
|
||||
|
||||
```
|
||||
Usage:
|
||||
|
||||
etcd-dump-logs [data dir]
|
||||
* Data dir is where the snapshots and WAL logs are located. The structure of the data dir should look like this:
|
||||
- data_dir/member
|
||||
- data_dir/member/snap
|
||||
- data_dir/member/wal
|
||||
- data_dir/member/wal/0000000000000000-0000000000000000.wal
|
||||
|
||||
Flags:
|
||||
|
||||
-entry-type string
|
||||
If set, filters output by entry type. Must be one or more than one of:
|
||||
ConfigChange, Normal, Request, InternalRaftRequest,
|
||||
IRRRange, IRRPut, IRRDeleteRange, IRRTxn,
|
||||
IRRCompaction, IRRLeaseGrant, IRRLeaseRevoke
|
||||
-start-index uint
|
||||
The index to start dumping
|
||||
-start-snap string
|
||||
The base name of snapshot file to start dumping
|
||||
-stream-decoder string
|
||||
The name and arguments of an executable decoding tool, the executable
|
||||
must process hex encoded lines of binary input (from etcd-dump-logs)
|
||||
and output a hex encoded line of binary for each input line
|
||||
```
|
||||
#### etcd-dump-logs -entry-type <ENTRY_TYPE_NAME(S)> [data dir]
|
||||
|
||||
Lists all the interested entries from WAL log.
|
||||
|
||||
```
|
||||
$ etcd-dump-logs -entry-type IRRTxn /tmp/datadir

||||

#### etcd-dump-logs -stream-decoder <EXECUTABLE_DECODER> [data dir]
|
||||
|
||||
Decode each entry based on logic in the passed decoder. Decoded status and decoded data are listed in separated tab/columns in the ouput. For parsing purpose, the output from decoder are expected to be in format of "<DECODING_STATUS>|<DECODED_DATA". Please refer to [decoder_correctoutputformat.sh] as an example.
|
||||
|
||||
However, if the decoder output format is not as expected, "decoder_status" will be "decoder output format is not right, print output anyway", and all output from decoder will be considered as "decoded_data"
