The panel and alerting rule should help to understand whether VM
component doesn't have enough CPU resources or gets throttled. The alert
is applicable for all VM components.
The panel was added to vmalert, vmagent, vmsingle, vm clusert and
victorialogs dashes.
-------------------
This alerting rule should have help us identify resource shortage for
sandbox vmagent - see [this
link](https://play.victoriametrics.com/select/accounting/1/6a716b0f-38bc-4856-90ce-448fd713e3fe/prometheus/graph/#/?g0.range_input=23d13h25m25s424ms&g0.end_input=2024-09-23T14%3A11%3A00&g0.relative_time=none&g0.tab=0&g0.expr=histogram_quantile%280.99%2C+sum%28rate%28go_sched_latencies_seconds_bucket%7Bjob%3D%22vmagent-monitoring-vmagent%22%7D%5B5m%5D%29%29+by+%28le%2C+job%2C+instance%29%29+%3E+0.1)
for example. We weren't aware of resource shortage, because VM metrics
assumed this vmagent had 1vCPU while in fact its limit was 0.2vCPU.

"description": "Shows the rate and total number of new series created over last 24h.\n\nHigh [churn rate](https://docs.victoriametrics.com/faq/#what-is-high-churn-rate) tightly connected with database performance and may result in unexpected OOM's or slow queries. It is recommended to always keep an eye on this metric to avoid unexpected [cardinality](https://docs.victoriametrics.com/keyconcepts/#cardinality) \"explosions\".\n\nThe higher churn rate is, the more resources required to handle it. Consider to keep the churn rate as low as possible.\n\nTo investigate stats about most expensive series use `api/v1/status/tsdb` handler. More details here https://docs.victoriametrics.com/cluster-victoriametrics/#url-format\n\nGood references to read:\n* https://www.robustperception.io/cardinality-is-key\n* https://valyala.medium.com/high-cardinality-tsdb-benchmarks-victoriametrics-vs-timescaledb-vs-influxdb-13e6ee64dd6b",

"description": "The percentage of slow inserts comparing to total insertion rate during the last 5 minutes. \n\nThe less value is better. If percentage remains high (>10%) during extended periods of time, then it is likely more RAM is needed for optimal handling of the current number of [active time series](https://docs.victoriametrics.com/faq/#what-is-an-active-time-series). \n\nIn general, VictoriaMetrics requires ~1KB or RAM per active time series, so it should be easy calculating the required amounts of RAM for the current workload according to capacity planning docs. But the resulting number may be far from the real number because the required amounts of memory depends on many other factors such as the number of labels per time series and the length of label values.

"description": "VictoriaMetrics limits the number of labels per each metric with `-maxLabelsPerTimeseries` command-line flag.\n\nThis prevents from ingesting metrics with too many labels. The value of `maxLabelsPerTimeseries` must be adjusted for your workload.\n\nWhen limit is exceeded (graph is > 0) - extra labels are dropped, which could result in unexpected identical time series. See more details about dropped labels in vminsert logs.",

"description": "Shows the number of concurrently executed read requests, where:\n* `max` - equal to `-search.maxConcurrentRequest` cmd-line flag;\n* `current` - current number of concurrent select requests executed by storage.\n\nEach concurrent select request requires RAM, CPU and disk IO resources during processing. Too many concurrent requests could result into OOM exceptions.\n\nWhen `current` hits `max` constantly, it means storage is overloaded and requires more CPU (see CPU usage) or disks with more IOPS (see disk writes and reads panels in Resource Usage row).\n\nSee more at https://docs.victoriametrics.com/cluster-victoriametrics/#resource-usage-limits",

All the other insert requests are queued for up to `-insert.maxQueueDuration` in the hope they will get a chance to be processed. This queue is used mostly for absorbing spikes for incoming insert request rate.\n\nWhen `current` hits `max` constantly, it means vminsert node is overloaded and requires more CPU or higher limits.",

Verify CPU/mem saturation of both components and network saturation between them.\nIf vminsert resources are saturated - consider adding more resources or scale vminserts horizontally.\n\nIf vminsert resources and network are fine, check vmstorage metrics for anomalies.",
