hello guys, is there any other way to define a timespan without using sequence in eql rules creation
Hey there @ima! 
So you can also use the ES Query DSL to constrain by time.
e.g.
GET /my-data-stream/_eql/search
{
"filter": {
"range": {
"@timestamp": {
"gte": "now-1d/d",
"lt": "now/d"
}
}
},
"query": """
file where (file.type == "file" and file.name == "cmd.exe")
"""
}
If this isn't exactly what you're looking for, could you provide a little more detail into the type of EQL query you're trying to write?
Cheers!
