Timechart, last value is always 0

Hi,

I have this query

index=os sourcetype=vmstat OR sourcetype=cpu OR sourcetype=df  host=betamax-admin   Filesystem="/dev/mapper/vg_betamaxadmin-lv_root" | timechart  span=5m max(PercentUsedSpace)

All it does it gets the % of diskspace used for a given host. Yet when I run it, the most recent value is always 0, which is odd. (see attached pic)

I wait a few minutes and try it again and the time changes but still the value is 0

It could be due to the last bin is partial and doesn't contain data, but based on your time range and when you executed the query, it got included in the result. The best option would to be use timechart option partial=false to remove any (generally first and last bin only) partial bins. See this for more info.
