Performance warnings and error states

The IAS client monitors various performance indicators. The indicators can cause warning and error statuses.

These indicators come in one of two forms:

Warning. This is marked by an orange background and icon and a notification message at the top of the page. This means that everything is still working normally, but you may see a performance error if you don't take action.
Error. This is marked by a red background and icon and a notification message at the top of the page. This means that all receiving and ingesting has stopped and won't restart until either:
- A two minute timeout has passed, or
- You correct the issue and click Retry in the page top notification bar message.

📘
The "two minute timeout" recycles until the issue is resolved. For example, if the issue resolves itself after the first two minute timeout, receiving and ingesting continues. If it doesn't, the two minute timeout resets and the process remains in "Error" status until resolved.

Type	Warning message	Description
Warning or error	Total bit rate is high	This status appears if the total bit rate for a single ias-worker is higher than recommended maximal total bit rate of 50 Mb. If the total bit rate reaches the upper limit of 75 Mb, averaged over a few tens of seconds, the state changes to red. Lower one or more bit rates, or split the ingested streams over several listening IP addresses and ports.
Warning or error	Cpu usage for ingesting high	This status appears if the CPU usage for an ingesting IAS thread is high. IAS is designed to have a low CPU usage. A high CPU load - for any reason - could lead to bad ingestion. It is expected that this happens when you ingest data with a very high bit rate or there are too many segments with sub-second lengths. If the CPU usage is really high then the state changes to red. Lower one or more bit rates, or split the ingested streams over several listening IP addresses and ports.
Warning or error	General memory usage is high	This status appears if the total memory usage of IAS is higher than expected. This happens if the bit rates are too high. If the memory usage is very high the status changes to Error (red). Lower one or more bit rates, or split the ingested streams over several listening IP addresses and ports.
