I'm trying to graph CPU temps in Chronograf from a different server on the network via the IPMI input in Telegraf.
It works fine doing the following query:
SELECT "value" FROM "telegraf"."autogen"."ipmi_sensor" WHERE time > :dashboardTime: AND ("entity_id"='3.2' OR "entity_id"='3.1') GROUP BY "entity_id"
However, in the graph the elements are named "entity_id=3.1" and "entity_id=3.2"
How can I rename those elements on the graph? I've tried this, but I'm not coming up with the right stuff:
SELECT "entity_id"='3.1' AS "CPU 1" AND "entity_id"='3.2' AS "CPU 2" FROM "telegraf"."autogen"."ipmi_sensor" WHERE time > :dashboardTime: GROUP BY "entity_id"
I'm sure this is a simple syntax fix, but I'm just learning here and I'm stumped.

I am running a JQL query to count how many issues have an empty value for the "Components" field versus how many issues have a non empty value for the "Components" field.
Here is the screenshot that I get for my 1st JQL query: category = "Cloud Services" and component is empty, the number of results is 6631:
Checking for null is equivalent to checling for empty, I have tried it and it returns the same.
Here is the screenshot for my 2nd JQL query: category = "Cloud Services" and component is not empty
The thing that confuses me is that I get 6631 results for my first query and I get 51372 results for my second result so 51372 +6631 = 58003
However, when I try to retrieve all the issues belonging to the Cloud Services category with this query: category = "Cloud Services", I get the following: I get 64879 as a result which does not match 51372 +6631 = 58003 computed above. Anyone knows why? Normally, the total number should correspond to the result of the 3rd screenshot since every issue contains components.
this only means, you have in the project more than 1 component, that is why the adds dont match.
with the REST api you can verify howmany and which components you have:
https://<host>/rest/api/latest/project/<project_id>/components
Could also be that one of the projects has a field configuration with the Components field hidden?
I was trying to write a simple FluxQL Query in Grafana Dashboard that uses a variable
m1(of type constant)(which contains the name of the measurement)
I created the variable m1 in grafana dashboard variables
m1 = my-measurement
and tried to run the following queries but non of them worked and they either say expression request error or No Data)
i.e
SELECT count("fails") FROM "/^${m1:raw}$/"
SELECT count("fails") FROM "/^${m1}$/"
SELECT count("fails") FROM $m1" (expression request error)
SELECT count("fails") FROM "$m1"
SELECT count("fails") FROM "${m1}"
The only query worked was without dashboard variables
SELECT count("fails") FROM "my-measurement"
How can I use the variables to work for that query.
On the similar ground I tried to make a custom variable(myVar) for which we take integer input values from user and on that basis where clause should work, but same error occurs either no data or expression request error
What I tried was
SELECT count(*) from "my-measurement-2" WHERE ("value" > $myVar)
How should I solve these issues?Please help
You may have a problem with
1.) syntax
SELECT count("fails")
FROM "${m1:raw}"
2.) data
You may correct query syntax, but query can be very inefficient. Query execution may need a lot of time - so it's better to have timefilter, which will use selected dashboard time range (make sure you have some data in that time range)
SELECT count("fails")
FROM "${m1:raw}"
WHERE $timeFilter
3.) Grafana panel configuration
Make sure you are using suitable panel - for query above Stat panel is a good option (that query returns only single value, not timeseries, so time series panel types may have a problem with that).
Generally, use query inspector to see how are variables interpolated - there can be "magic", which is not obvious - e.g. quotes which are added around numeric variables, so then it is string filtering and not numeric filtering on the InfluxDB level.
I'm trying to leverage my moderate SQL-knowledge for InfluxQL, but I'm missing something(s) about the nature of timeseries db.
Use case
I write a measurements from our issue tracker, when an issue is updated:
issue_updated,project=facebook,ticket=fb1,assignee=coolman status="todo"
Problem
Given this returns rows of issues statuses:
SELECT status
FROM "issue_updated"
If this was SQL (fiddle) I would use COUNT(and then add the WHERE time > NOW() - 1Y GROUP BY time(5m)). However the following gives me Mixing aggregate and non-aggregate queries is not supported
SELECT status, count(status) as 'Count'
FROM "issue_updated"
Can someone give some guidance here? ta
Sounds like what you're looking for is the ability to group by a field value which isn't currently supported.
From what I can tell, if you modify your schema a bit, it should be possible to do what you're looking. Instead of
issue_updated,project=facebook,ticket=fb1,assignee=coolman status="todo"
Do
issue_updated,project=facebook,ticket=fb1,assignee=coolman,status=todo value=1
then
SELECT count(value) FROM "issue_updated" WHERE time > now() - 52w GROUP BY status
name: issue_updated
tags: status=other
time count
---- -----
1449523659065350722 1
name: issue_updated
tags: status=todo
time count
---- -----
1449523659065350722 2
should work.
I have the following monitoring stack:
collecting data with telegraf-0.12
storing in influxdb-0.12
visualisation in grafana (3beta)
I am collecting "system" data from several hosts and I want to create a graph showing the "system.load1" of several host NOT merged. I though I could simply add multiple queries to the graph panel.
When creating my graph panel, I create the first serie and see the result but when I add the second query, I got an error.
Here is the panel creation with 2 queries
Here is the query generated by the panel:
SELECT mean("load1") FROM "system" WHERE "host" = 'xxx' AND time > now() - 24h GROUP BY time(1m) fill(null) SELECT mean("load1") FROM "system" WHERE "host" = 'yyy' AND time > now() - 24h GROUP BY time(1m) fill(null)
And the error:
{
"error": "error parsing query: found SELECT, expected ; at line 2, char 1",
"message": "error parsing query: found SELECT, expected ; at line 2, char 1"
}
So I can see that the generated query is malformed (2 select in one line without even a ';') but I don't know how to use Grafana to achieve what I want.
When I show or hide each query individually I see the corresponding graph.
I have created a similar graph (with multiple series) with chronograf but I would rather use grafana as I have many more control and plugins...
Is there something I am doing wrong here ?
After reading couple of thread in github issues, here is a quick fix.
As mentionned by #schup, the problem and its solution are described here:
https://github.com/grafana/grafana/issues/4533
The binaries are currently not fixed in grafana-3beta (if might in the next weeks). So there are 2 options: fixing the source and compile or patched an existing install.
I actually had to patch my current install:
/usr/share/grafana/public/app/app.<number_might_differ_here>.js
sed --in-place=backup 's/join("\\n");return k=k.replace/join(";\\n");return k=k.replace/;s/.replace(\/%3B\/gi,";").replace/.replace/' app.<number_might_differ_here>.js
Hope this might help (and that it will soon be fixed)
Seems to be an API change in influxdb 0.11

I want to make a few customizations to jQuery UI Autcomplete:
1) If there are no results found it should output "no results found" in the list.
2) Is it possible to highlight/bold the letters in the results as they are being typed? For example if I type "ball" and I have "football" in my results it needs to output as foot ball
3) Is it possible for the results that appear at the top to match the beginning of the string. For example suppose I have 3 entries in my database:
Astrologer
Space Station
Star
I start typing "st" - this will bring up those 3 entries in that order. But I want "Star" to be the first result.
The MySQL query being used at the moment to generate the results is:
$query = mysql_query("SELECT id, name FROM customer WHERE name LIKE '%".$_GET['term']."%' ORDER BY name");
You can simply echo 'No results found' inside the script that returns the list if num rows from your mysql_query is 0.
This was possible in the original Autocomplete plugin but I can't see it anywhere in the JQuery UI documentation.
You may have to run two separate mysql queries - the first one looking for LIKE '".$_GET['term']."%' and the second one as you have it, but excluding the results you've already got from the first query.
