Block Anomaly

​

Functionality

• Conditions for min and max transaction count in a block
• Conditions for min and max gas used in a transaction. Use GasMonitor for more gas related monitors
• Conditions for min and max events count in a block
• Conditions for block size (min/max)
• Large and small Gas usage in block
• Expected Block frequency (max/min) (msec). This informaiton is extracted from block timestamps.
• Liveness check for block generation. Alert is triggered if no blocks are generated within the conditiion (E.g. > 25000 means block is expected within 25 sec )
• Track block latency. It is updated evey 10 min

​

Configuration

• Transactions min (tx_min, default: <1): Minimal transaction in block
• Transactions max (tx_max, default: >2000): Maximal transaction in block
• Events min (event_min, default: <1): Minimal Events in block
• Events max (event_max, default: >3000): Maximal Events in block
• Block size min (block_min, default: <100): Minimal block size
• Block size max (block_max, default: >10000000): Maximal block size
• Gas min (gas_min, default: <22000): Minimal gas used in a block
• Gas max (gas_max, default: >29999000): Max gas used in a block
• Gas min (Tx) (tx_gas_min, default: <20000): Minimal gas used in a Transaction
• Gas max (Tx) (tx_gas_max, default: >10000000): Max gas used in a Transaction
• Cron (cron, default: 60 sec): Periodic check for anomalies See common configuration.
• Track Latency (lat_enabled, default: False): Track Blocks Latency
• Block Freq (min) (block_freq_min, default: <1000): Min Block creation interval
• Block Freq (max) (block_freq_max, default: >12500): Max Block creation interval
• Liveness interval (liveness, default: > 25000): Liveness interval threshold
• Severity (severity, default: -1.0): Severity See common configuration.
