Values displayed wrong in email alert

Hello, I have a problem with my alerts. I manage to configure my grafana so that it sends alerts through email from a query in mysql.

The alert works perfectly but the data displayed is wrong, for each number it adds a decimal point that does not exist and 3 zeros that only cause confusion of the data. as it is possible to correct this error?, i see the json and the data is correct, there must be an error in the template

Hi @maximilianoalbert,

Can you share more details about your JSON and the datasource? What does the data look like when you query it? How does it appear in a panel?

this is an example from test alert:

firing:true

state:“pending”

conditionEvals:“true = true”

timeMs:“2.848ms”

matches:Array[23]

0:Object

metric:“156 - Cese del Regimen (Inscriptos)”

value:1786

1:Object

metric:“194 - Inscriptos sin actividad principal (Inscriptos)”

value:2676

2:Object

metric:“25 - Vinculos sin Responsabilidad (Objetos)”

value:517

3:Object

metric:“44 - Saldo Negativo obligacion (Obligaciones)”

value:733

4:Object

metric:"47 - Obligaciones con estado material ANUL o APEX (Obligaciones) "

value:419

5:Object

metric:“195 - Inscriptos con mas de una actividad como principal (Inscriptos)”

value:6253

this is pannel json:

this is the pannel:

Hi @maximilianoalbert,

thanks for sharing–that is strange, and I’ll look into this. In the meantime, I wanted to let you know that Grafana 8 will be released in two weeks, and it should ship with major improvements to alerting

hi, i tried with different versions and the problem keeps appearing, i tried to see the json from alert panel and i get this eg:

Object
firing:true
state:"pending"
conditionEvals:"true = true"
timeMs:"1.972ms"
matches:Array[1]
0:Object
metric:"44 - Saldo Negativo obligacion (Obligaciones)"
value:681
logs:Array[3]
0:Object
message:"Condition[0]: Query"
data:Object
1:Object
message:"Condition[0]: Query Result"
data:Object
meta:Object
series:Array[1]
0:Object
2:Object
message:"Condition[0]: Eval: true, Metric: 44 - Saldo Negativo obligacion (Obligaciones), Value: 681.000"
data:null

in some place the object is changed and added some zeros

Hi @maximilianoalbert

Have you tried using the new Unified Alerting in Grafana 8? It’s still behind a feature toggle but is a large improvement on our alerting platform:

You can pass the feature toggle as an environemnal variable or update it in your configuration file:

docker run -p 3000:3000 -e "GF_FEATURE_TOGGLES_ENABLE=ngalert" grafana/grafana:latest

Hi @maximilianoalbert
i have the same problom in grafana 8.2.2

did you find solution?

how could the value that shows in email alert change without decimal

value
73.000

Hi @rahelask4 i never found the solution, values are changed when grafana values the alert

Just to make sure we’re all on the same page here, are you both using the new Grafana 8 alerts and still having this problem? As a reminder, you have to enable it explicitly still by either setting the env_var or feature toggle (in the grafana.ini)

hi @davidparrott i did a new try. installed grafana 8.2 (lastest) in my computer, setted the datasource, setted the smtp config and setted a new alert panel for test. and the result is this:


here i show you that alerting is enabled.
Screen Email
still getting errors in my values, my values are integer, not doubles. i never use a double in all the database.

the value for 139 must be 323 not 323K !!!
