Here in 1st one, 18= cpu usage, 19=memory usage,13=disk usage
like this i have 24 hours data.In single event the server name,node name, cpu, memory,disk usage are there with comma separator.

start with this...
your base search
| rex "(AM|PM)\s+(?<SERV>[^,]+),\s+?(?<NODE>[^,]+),\s+?(?<mydate>[^,]+),\s+?(?<mytime>[^,]+),\s+?(?<CPU>\d+),\s+?(?<MEM>\d+),\s+?(?<DISK>\d+)"
| bin _time as desired_times span=4h
| where _time = desired_times
| table _time SERV NODE CPU MEM DISK
...then any one of these...
| timechart max(CPU) as CPU by SERV
| timechart max(MEM) as MEM by SERV
| timechart max(DISK) as DISK by SERV
The | bin _time as will create a new field with the 4-hour increment to compare against.
