Docker Image: `docker.replex.io/replex/k8sagent-go:1.7.12` ## 1.7.11 - 2020-12-07 * Sets the default Prometheus node label to `node` (previously `instance`). Docker Image: `docker.replex.io/replex/k8sagent-go:1.7.11` ## 1.7.10 - 2020-11-10 * Bug fix in node CPU usage calculation. Docker Image: `docker.replex.io/replex/k8sagent-go:1.7.10` ## 1.7.9 - 2020-11-09 * We now use actual node CPU usage instead of the sum of the container CPU usage. This helps to account for CPU usage by non-container workload. * Adds support for failed metrics synchronization on disk. * By setting the environment variable `METRICS_CACHE_DISK` to either `true/false`, you can specify whether the metrics are cached on disk or in memory. By default, `true`. * If metrics are cached on disk, you can specify the path on disk by setting the environment variable `METRICS_CACHE_DISK_DIR`. By default, `/data/metrics`.

First one stands for the amount of metrics that are waiting to be re-sent, second one represents the total count of once failed metric push. Docker Image: `docker.replex.io/replex/k8sagent-go:1.7.8` ## 1.7.7 - 2020-10-14 * Adds a new optional environment variable: `METRICS_FILESYSTEM` to specify the filesystem metric source. Options: `cadvisor`, `csi`.
