hey @aluode99
this log record appears during scrape configs reloading
could you please share info about CPU, memory usage?
which VMAgent version are you using?
could you please describe a setup you're running it in?
from victoriametrics.
hi @AndrewChubatiuk thank you for your reply.The detailed configuration for vmagent is as follows:
version:v1.96.0
cpu: 18c
memory: 16G
cluster membersCount: 19
cluster replicationFactor: 1
CPU utilization rate:
The use case involves loading kubernetes_sd_configs through a sidecar, and then invoking vmagent reload to load the configuration. When the pod starts, kubernetes_sd_configs is empty,so the service discovery takes 0 seconds. After the sidecar loads the configuration, vmagent reloads and the service discovery takes 2061 seconds.
Due to the kubernetes_sd_configs being empty at startup, the startup process remains blocked at the code checkpoint 1 and does not proceed to the reload process at checkpoint 2. As a result, vmagent does not incrementally load the configuration to gradually activate the collection tasks. Instead, it spends 2061 seconds to complete the discovery of all targets before beginning the collection tasks, leading to a 2061-second period without data collection.

How much time takes the next configuration update after initial one?
Could you please share information about etcd and kube api request duration?
from victoriametrics.
I have compiled the duration of some reloads, with a total time of about 7 minutes. The shortest duration was 0.002 seconds, and the longest was 1.139 seconds. The detailed durations are as follows:
