graphite

I'm using graphite to collect data, and I'd like to retrieve the total count of certain events over a period of time. Say, number of logins per week. However, I just need the total number, and don't need to see how it evolves over time. When I use something like from=-1w&target=summarize(stats.events.login.success,"1w")&format=json then I still get two datapoints, and not one. Is there a way to get a single datapoint from the summarize function? or use a different function to return a single datapoint value? The problem here is that summarize doesn't align to the from field by default.

I would like to put two series in the same graph on the graphite dashboard . However, since the dashboard requires single-line commands I could not find a way that doesn't involve the use of a wildcard. Here's an example of the two series I would like in the same graph: sum(base.foo.bar.positive.*) sum(base.foo.bar.negative.*) I tried several separators but I could not get it to work. Any ideas? dannyla You have a few options here... Merge the 2 graphs on to the graph via the drag and drop in the dashboard OR Use the sumSeriesWithWildcards () function Merge 2 or more wildcard matching Open

I am trying to delete some old graphite test whisper metrics without any success. I can delete the metrics by removing the files. (See: How to cleanup the graphite whisper's data? ) But, within a few seconds of blowing away the files they regenerate (they are empty of metrics and stay that way since nothing is creating new metrics in those files). I've tried stopping carbon (carbon-cache.py stop) before deleting the files, but when I restart carbon (carbon-cache.py --debug start &) they just come back. How do I permanently delete these files/metics so they never come back? Are you running

I'd like to roll up all statistics matching a certain pattern ( stats.timers.api.*.200.count , for example). Is that possible within Graphite? If not, are there other systems that I should be looking at that can generate that type of roll-up data from statsd ? Or is this the sort of thing that I should do within my statsd configuration directly? 回答1: If you after a blanket sum of all the data that matches, then you can

Ideally we would have the days of the week (Monday,Tuesday...etc) on the x axis labels, and then seven bars in the graph, one for each day of the week. I can't seem to change the X axis at all though. Thoughts: I could cook the time data, and send it a fixed time since epoch value, but this results in a very thin bar on the grafana page. I could write a script to send a huge amount of metrics with seconds since epoch values representing the

With this format: "user_login 1 13xxxxxxx" (key value timestamp) My problem is Graphite give me a graph with only a line with the value "1", each minute. I send a random number of messages each minutes (between 6 and 60), but I think Graphite limits to the first (or last?) message, to display a value. How to do to have an sum of each message, each minute ? 回答1: You could also try carbon aggregation service so that metrics are aggregated when they are collected instead of in the Graphite
