# Redis Inspection

Redis CLI commands for inspecting caches and buffers.

## Connecting to Redis

```bash
redis-cli
# Or with password
redis-cli -a yourpassword
```

## Transaction Buffer

**View buffer size**:

```
LLEN site:observatory:transaction_buffer
```

**View buffered transactions**:

```
LRANGE site:observatory:transaction_buffer 0 -1
```

**View specific transaction**:

```
GET site:observatory:transaction:abc-123-def
```

## Failed Transactions

```
LLEN site:observatory:failed_transactions
LRANGE site:observatory:failed_transactions 0 -1
```

## Buffered Data Cache

```
KEYS site:observatory:buffered:*
GET site:observatory:buffered:ExecutedObsUnit:uuid
```

## Read Buffer

```
KEYS site:observatory:read_buffer:*
HGETALL site:observatory:read_buffer:ExecutedObsUnit:uuid
```

## Monitoring

**Monitor all commands**:

```
MONITOR
```

⚠️ **Warning**: `MONITOR` impacts performance. Use carefully in production.

**Memory usage**:

```
INFO memory
```

**Database size**:

```
DBSIZE
```

## Clearing Caches

⚠️ **Warning**: Only for development/testing. Never in production without understanding impact.

```
# Clear specific key
DEL site:observatory:buffered:ExecutedObsUnit:uuid

# Clear pattern (use with extreme caution)
# First list keys
KEYS site:observatory:buffered:*
# Then delete if appropriate
```
