QUESTION
I am new with Loki and have made an alert in Loki but I don't see any notification in the Alertmanager. Loki is working fine (collecting logs), Alertmanager also (getting alerts from other sources), but the logs from loki don't get pushed to alertmanager.
Loki config:
...ANSWER
Answered 2021-May-06 at 12:12The config looks good, similar as mine. I would troubleshoot it with following steps:
Exec to docker container and check if the rules file is not empty
cat /etc/loki/rules/rules.yaml
Check the logs of loki. When rules are loaded properly logs like this will pop up:
QUESTION
We are testing our Hadoop applications as part of migrating from Hortonworks Data Platform (HDP v3.x) to Cloudera Data Platform (CDP) version 7.1. While testing, we found below issue while trying to create Managed Hive Table. Please advise on possible solutions. Thank you!
Error: Error while compiling statement: FAILED: Execution Error, return code 40000 from org.apache.hadoop.hive.ql.ddl.DDLTask. MetaException(message:A managed table's location should be located within managed warehouse root directory or within its database's managedLocationUri. Table MANAGED_TBL_A's location is not valid:hdfs://cluster/prj/Warehouse/Secure/APP/managed_tbl_a, managed warehouse:hdfs://cluster/warehouse/tablespace/managed/hive) (state=08S01,code=40000)

...ANSWER
Answered 2021-Apr-13 at 11:18hive.metastore.warehouse.dir
- is a warehouse root directory.
When you create the database, specify MANAGEDLOCATION
- a location root for managed tables and LOCATION
- root for external tables.
MANAGEDLOCATION
is within hive.metastore.warehouse.dir
Setting the metastore.warehouse.tenant.colocation
property to true
allows a common location for managed tables (MANAGEDLOCATION) outside the warehouse root directory, providing a tenant-based common root for setting quotas and other policies.
See more details in this manual: Hive managed location.
QUESTION
I have configured PLG (Promtail, Grafana & Loki) on an AWS EC2 instance for log management. The Loki uses BoltDB shipper & AWS store.
Grafana - 7.4.5, Loki - 2.2, Prommtail - 2.2, AlertManager - 0.21
The issue I am facing is that the Loki does not trigger or push alerts on alertmanager. I cannot see any alert on the AlertManager dashboard though I can run a LogQL query on Grafana which shows the condition was met for triggering an alert.
The following is a screenshot of my query on Grafana.
The following are my configs.
- Docker Compose

QUESTION
I am using the promtail helm chart to connect to a Loki server running on a different stack. I have Loki behind an Nginx ingress secured with basic auth.
I can't find any documentation on this, and it's very possible it's just my admittedly limited understanding of helm.
I'm simply trying to use basic auth to connect to the Loki instance while using a Kubernetes secret instead of plaintext credentials in the helm values
This works perfect:
...ANSWER
Answered 2021-Mar-09 at 08:08To give a bit of background to anyone new to Loki, as stated in the documentation: Loki does not come with any included authentication layer. Operators are expected to run an authenticating reverse proxy in front of your services, such as NGINX using basic auth or an OAuth2 proxy.
This basically means that you'll have to place something in between the client(s) and Loki to enforce e.g. basic authentication. In this case there's a Ingress (Nginx) acting as a reverse proxy with basic authentication.
To troubleshoot problems with authentication using Nginx there's a number of things to check:
- Logs of the Nginx Ingress Pod, check for authentication errors.
- That the added Kubernetes Secret contains what you expect.
- That you have configured the Ingress object with the needed
annotations
.
When it comes to using Nginx as Ingress and adding basic authentication this resource from the official docs is really helpful.
In general when creating Kubernetes secrets, especially from the command line using kubectl
you'll have to single quote the password if it contains special characters. This is so that the special characters wont be interpreted by your shell. More info here.

I am new to React and practicing data transfers with form. I have a basic form like this.
I want users to select an appliance from the dropdown menu and enter the zip code. When they click on go, they are redirected to another page that has other details to be filled out. like this:
Now the second page can be accessed from other links where they may not have filled the two inputs before, so what I want is for users is to get the two inputs preloaded on the second form so as to avoid wasting time. Something like this:

QUESTION
I am trying to make a simple trivia quiz inside of a GUI but I cannot seem to update the window so that it goes on to the next question. I have been trying for a while and whatever solution I come up with either works in part or crashes the window! Wondering if anyone could give me an idea of how to update the current window to show the following question?
...ANSWER
Answered 2020-Aug-31 at 12:59A few things:
- The input box name should be a generic name like 'question' since you will use the box for every question.
- Use the loop to go through the question list, updating the text box after each correct answer
- Access the question data through the question object instead of using the multiple_choice list
Try this code:
QUESTION
So I ran into some problem when I tried to get information from an API, I can grab the names of each product, but well for one: When I try to return the "float" value (the price of the product) I get this error: TypeError: 'float' object is not iterable
This is my Python code:
...ANSWER
Answered 2020-May-20 at 18:29It looks like buyPrice
is a single float value, corresponding to 12.7
in the data you give us. Then, in your template, you're trying to iterate over it by doing for price in buyPrice
, which throws the error.
Depending on what you want to do, you should either extract the pricePerUnit
values into an array that you can then use in the template, or modify the template to expect only a single float value.
QUESTION
Is there any way to produce a message in the kafka-console-producer with a null value (ie. mark it for the compactor to delete it with a tombstone)?
I've tried producing "mykey" and "mykey|". The former produces an error and the later makes the value the empty string. Running producer like this:
...ANSWER
Answered 2018-Aug-28 at 12:22Unfortunately, there is no way to do that using console-producer
this is a code snippet from ConsoleProducer class (how it reads the data). Kafka 0.11.0 (don't think that it was changed significantly between different versions).
