Number of connects / disconnects of clair during 24h to postgresql
ohauer opened this issue · comments
Description of Problem / Feature Request
after installing quay.io/coreos/clair:v4.3.5 and connected to postgresql we saw in our monitoring a high increase of connects/disconnects rate from clair to postgres.
add the following lines to file postgresql.conf
log_connections = on
log_disconnections = on
log_duration = on
log_line_prefix = '%m [%p] %u %d %h 'we count 410.586.268 connects/disconnects during 24h from clair in idle state (no scans done during this time)
Expected Outcome
A magnitude lower connections during 24h in idle state
Actual Outcome
Nothing special in clair logs
Environment
Calir4 installed as docker container on VM and as container in K8s
- Clair version/image: quay.io/coreos/clair:v4.3.5
- Clair client name/version: NA
- Host OS: Ubuntu 20.04.3 LTS
- Kernel: 5.4.0-96-generic
- Kubernetes version: v1.20.14
- Network/Firewall setup: NA
We will do an update to 4.3.6 to see if we get lower numbers
How often are updaters run? How many Clair instances? How many concurrent connections are made per instance?
Will close shortly if there's nothing more to report.
