Features:

• Live Monitoring
• Low CPU utilization
• Prometheus Exporter
• Basic-Auth protection
• Top commands of count
• Top command and keys count
• No dependencies
• No Redis performance degradation

Tasks:

• Count commands and arguments
• Count network traffic of command
• Monitor Slow commands
• Monitor big response

Installation

• redis-traffic-stats_linux_amd64

Usage

./redis-traffic-stats --interface=ens5 --addr=:9200 \
--password=pass \
--debug=false \
-s=: \
-r="[0-9a-fA-F]{8}\-[0-9a-fA-F]{4}\-[0-9a-fA-F]{4}\-[0-9a-fA-F]{4}\-[0-9a-fA-F]{12}" \
--redisport=6379 \
--max=150 \
--slow-response-threshold=20ms
--snaplen=50000

Flag	Default	Usage
debug	false	Enable debug logs
interface	empty	Ethernet infreface name. eth0, ens5
redisport	6379	Redis server port number
addr	:9200	http listener port for prometheus metrics
username	admin	Prometheus metrics username
password	****	Prometheus metrics password
s	empty	Separator of keys (for split). If it empty does not split keys.
r	empty	Regex pattern of keys (for clean)
max	150	Maximum lookup size of key. If value -1 unlimited lookup.
slow-response-threshold	500	threshold for recording slow response. Millisecond
big-response-threshold	1500	threshold for recording slow response. Bytes
snap	2048	the maximum size to read for each packet (snaplen)

Grafana Dashboard

This easy way for dasboarding. You can upload to grafana this file.

Run test environment

docker-compose up

garafana:

http://localhost:3000/

prometheus:

http://localhost:9090/

Static Compilation

This tool require libpcap library (https://www.tcpdump.org/). You can embed dependencies on the compilation process. This helps for portability. Check the build command below

LDFLAGS='-l/usr/lib/libpcap.a' CGO_ENABLED=1 go build -ldflags '-linkmode external -extldflags -static' .

Troubleshooting

If you get an error about libpcap like below

./redis-traffic-stats: error while loading shared libraries: libpcap.so.0.8: cannot open shared object file: No such file or directory

install libpcap

for centos

yum install libpcap-devel
