I found that the search-queued-tasks was usually more than 1000.
There are several visualizes in my dashboard. Each of them set an aggregation at least. I have no idea what caused this issue.
Is this situation normal？
How many shards are you typically searching with these dashboards?
There are six visualizes in my dashboard. Each of them set an aggregation at least.
The dashboard monitors a special index by daily and refreshes the dashboard page automatically by each 5 seconds .
The data of this index is split by daily. So the index pattern is like 'indexname.yyyy.mm.dd'.
Each index in elasticsearch has 5 shards.
The environment of my elasticsearch is non-clustered. Because it has only one node.
How long does the dashboard take to reload? What is the specification of the node? How many days is the dashboard querying?
The dashboard take less than 1 second to reload.
As usual, the dashboard load data by current date.
Please check the specification of the node below:
4 core cpu
16G ram
window 2008(a virtual machine hosted on aliyun.com)
I set 8G ram by config the panel of elasticsearch-service to start up the elasticsearch service.
I have set the 'thread_pool.search.queue_size' up to 3000 this morning.
It seems that the kibana works well.
But I still have a little concern about the reason why the number of 'search-queued-tasks' is so high.
