I'm newbie with Kibana and I tried to get a line graph with CPU ressource (system or user) but values are in number type (between 0 and 1).
I want to multiply by 100 with a scripted field (painless language) but when I did :
return doc['system.memory.used.pct'].value.multiply(100)
or
return 100 * doc['system.memory.used.pct'].value
Values are completly wrong (for exemple 0.964 becomes 2.536, instead of 96.4)
Did I miss something ?
Here the screenshot of my visualization :
I'm slightly surprised that this doesn't work out of the box. If the values are really in percent (and the field ends in .pct), I think this should just work out of the box. See my example below:
Update:
And here is the same visualization you're using. I only have a single host, but this is just working out of the box:
This is the underlying data in Discover:
And here is the index pattern:
I'd especially make sure that the index pattern is the same — both data type and format.

I wrote my own munin-plugin and I'm confused, how munin represents values between 0 and 1.
The 2nd line of values uses an notation with 'n'. What does it mean and how can I avoid it? I just want a common floating point value like 0.33!
What I'm doing wrong?
Here is the plugin configuration:
graph_title Title
graph_args --base 1000 -l 0
graph_vlabel label
graph_category backup
Every hint is welcome.
UPDATE
Ok, I finally found it: https://serverfault.com/questions/123761/what-does-the-m-unit-in-munin-mean
'm' stands for milli!
I am a bit confused, why munin is using it in this context!
Is there any possibility to avoid this?
Some configuration items that may be of interest. See Munin Plugin Reference.
You may change the resolution in numeric resolution in the table data with the below. Use C/C++ formatting, and spacing may be an issue in end result.
graph_printf %5.2le # default is %6.2lf
# appears l (for long) is needed
For certain graph types you can also alter the display period for the munin graph. Munin graphs the average data between last two (nominally 5 minute spaced) measurements - with default of per/sec units on the result. This is based on the var.type attribute which defaults to GAUGE. If your for example data is reporting accumulated counts you can use:
type DERIVE # data displayed is change from last
# reading
type COUNTER # accumulating counter with reset on rollover
for each of these you can change the vertical axis to use per/minute or per/hour with:
graph_period minute # if type DERIVE or COUNTER
# display avg/period vs default of avg/sec
Note that the table shows the derived data for the graph_period.
See RRDCreate == rrdtool create for implementation particulars- munin used rrd underneath.
I'm trying to start traversing from one set of labelled vertices, then get all their in-vertices connected by a particular kind of edge, then from there, return a property of those in-vertices as objects. I can do this same thing with some out-vertices starting from the same set of labelled vertices with no problem, but get a "The provided traverser does not map to a value:" error when I attempt it with some in-vertices.
I have found a workaround, but it is not ideal, as it returns the desired property values as arrays of length one.
Here is how I do the very similar task successfully with out-vertices:
g.V().hasLabel('TestCenter').project('address').by(out('physical').project('street').by(values('street1')))
This returns things like
==>{address={street=561 PLACE DE CEDARE}}
==>{address={street=370 N BLACK STATION AVE}}
This is great!
Then I try the same sort of query with some in-vertices, like this:
g.V().hasLabel('TestCenter').project('host').by(__.in('hosts').project('aCode').by(values('code')))
and get the above mentioned error.
The workaround I've been able to find is to add a .fold() to the final "by" like this:
g.V().hasLabel('TestCenter').project('host').by(__.in('hosts').project('aCode').by(values('code')).fold())
but then my responses are like this
==>{host=[{aCode=7387}]}
==>{host=[{aCode=9160}]}
What I would like is a response looking like this:
==>{host={aCode=4325}}
==>{host={aCode=1234}}
(Note: I am not sure if this is relevant, but I am connecting Gremlin to a Neptune DB Instance)
It seems to me from the error above and your workaround that not all of your 'TestCenter' have an in edge from type 'hosts'. When using project the by have to map for a valid value.
you can do two things:
1) make sure a value will be returned in the project:
g.V().hasLabel('TestCenter').project('host')
.by(coalesce(__.in('hosts').project('aCode').by(values('code')), constant('empty')))
2) filter does values:
g.V().hasLabel('TestCenter').where(__.in('hosts'))
.project('host').by(__.in('hosts').project('aCode').by(values('code')))
I'm trying to divide 2 series to get their ratio.
For example I'm got sites (a.com, b.com, c.com) as * (All sites)
Each of them has total sections count and errors occurred stats. I'm wanna to show as bars errors/sections where section > errors for each site to each erros for this site. Here I'm whant to got 3 bars.
So:
A parser.*.sections.total
B parser.*.errors.total
X-Axis Mode:Series
Display:DrawMode: Bars
When i'm trying to use divideSeries I'm always got VallueError(divideSeries second argument must reference exactly 1 series)
A new function divideSeriesLists was introduced in Graphite 1.0.2 for dividing one series with another. Both the series should be of same length.
You can use mapSeries with divideSeries to do vector matching of series in Graphite (or maybe asPercent depending on which version of graphite you are using).
An example query:
aliasByNode(reduceSeries(mapSeries(groupByNodes(parser.*.{sections,errors}.total, 'maxSeries', 1, 2), 0), 'asPercent', 1, 'sections', 'errors'), 0)
I'm not sure what aggregation function you are using so substitute maxSeries for the function you need.
Check out this blog post about using mapSeries with divideSeries for more explanation.
Here is an example from our system in the Grafana query editor:
im trying to find an easy formula to do the following:
=IF(AND(H6="OK";H7="OK";H8="OK";H9="OK";H10="OK";H11="OK";);"OK";"X")
This actually works. But I want to apply to a range of cells within a column (H6:H11) instead of having to create a rule for each and every one of them... But trying as a range:
=IF(AND(H6:H11="OK";);"OK";"X")
Does not work.
Any insights?
Thanks.
=ArrayFormula(IF(AND(H6:H11="OK");"OK";"X"))
also works
arrayformulas work the same way they do in excel... they just need an ArrayFormula() around to work (will be automatically set when pressing Ctrl+Alt+Return like in excel)
In google sheets the formula is:
=ArrayFormula(IF(SUM(IF(H6:H11="OK";1;0))=6;"OK";"X"))
in excel:
=IF(SUM(IF(H6:H11="OK";1;0))=6;"OK";"X")
And confirm with Ctrl-Shift-Enter
This basically counts the number of times the said range is = to the criteria and compares it to the number it should be. So if the range is increased then increase the number 6 to accommodate.
I am using Robot Framework Selenium using python. I need help with grabbing a certain part of the string, without getting an exterior library. lets say the text says " Your range price for your product is from $0- 400" So i want to be able to get the 400 and paste is somewhere else in the test. The number isnt always 400 sometimes it may be 55 or something different. So i think i would need a GET TEXT Starting from the dollar sign count two spaces and take whatever is left. or i can get the first number and add 10. Like in this example its 0 so i want it to paste 10. Please Let me Know!
"Fetch From Right" should cover that. You just have to identify the stop point, which in your example looks like it would be the hyphen between the two number values.
for example: to extract the last five digits of this string ABC12345 you would want to create a variable to assign the text to.
${number}= Get Text (defined location of text, minus parentheses)
Then use this command to retrieve the remainder of the string after your identified stop point (C).
${desiredNumber}= Fetch From Right ${number} C
This is essentially creating a new variable, which is defined as the extracted values from the original variable after that point.
Hopefully this helps.
You could use the built-in function Evaluate to use the python underlying system:
${my_string} Get Text <your-identifier-here>
${result} Evaluate ${my_string}[${my_string}.rfind('-') + 1:]
Also, please have a look if you can use one of the standard available libraries: http://robotframework.org/robotframework/
