Prometheus metric retruns no data - devops

i have installed the prometheus-es-exporter for querying the elasticsearch and also i have written some queries.E.g one of the query looks like:
[query_database_connection_exception]
QueryIntervalSecs = 300
QueryIndices = logs.*
QueryJson = {
"size": 0,
"query": {
"query_string": {
"query": "message: \"com.microsoft.sqlserver.jdbc.SQLServerException: \" AND #timestamp:(>=now-1h AND <now)"
}
},
"aggs": {
"application": {
"terms": {
"field": "kubernetes.labels.app.keyword"
}
}
}
}
ES-Exporter exposes after the configuration the metric database_connection_exception_application_doc_count but i face the issue that sometimes i get in prometheus the error message:
This happens not only for this query but for other queries as well.My understanding and expectation is that if my query does not find the string com.microsoft.sqlserver.jdbc.SQLServerException for the last 1h it must return the value=0 in prometheus but for some reason it returns no data.How should i understand this?
ES-Exporter is running smoothly,health check of ES-Exporter and Elastic shows no error,all elastic nodes are at state green.

Google Slides API reports Invalid requests[0].updateTableCellProperties: Invalid field: table_cell_properties

Trying to troubleshoot an error message my app gets after sending a batchUpdate request to Google Slides API
Invalid requests[19].updateTableCellProperties: Invalid field: table_cell_properties
The 19th request in the batch is the only updateTableCellProperties request I have. If I removing the 19th request from the batch, everything works fine.
Other requests which I run in this batchUpdate with no issues are are insertTableRows, deleteTableRow, insertText, updateParagraphStyle, updateTextStyle, updateTableColumnProperties. They all work on the same table, so I use the same objectId, but depending on the request I have to specify it as tableObjectId instead of objectId.
Unsure if I am generating a wrong request for the only updateTableCellProperties request I have, or if there is a problem in the Google Slides ruby gem itself, I tried sending just this updateTableCellProperties request from the Google Slides API explorer which has some validation on the request structure. So I sent this updateTableCellProperties batchUpdate request
{
"requests": [
{
"updateTableCellProperties": {
"objectId": "gf9d8fea71f_22_1",
"tableRange": {
"location": {
"columnIndex": 0,
"rowIndex": 1
}
},
"fields": "tableCellProperties",
"tableCellProperties": {
"tableCellBackgroundFill": {
"solidFill": {
"color": {
"themeColor": "LIGHT1"
}
}
}
}
}
}
]
}
And I got this error:
{
"error": {
"code": 400,
"message": "Invalid requests[0].updateTableCellProperties: Invalid field: table_cell_properties",
"status": "INVALID_ARGUMENT"
}
}
Why is this updateTableCellProperties request reported as invalid? I am also confused by the output of the error message as it mentions table_cell_properties in snake case, while the documentation only mentions tableCellProperties in camel case, and my request also only mentions tableCellProperties in camel case. I am only aware of the ruby gems translating between snake case and camel case, but this is not relevant to the API Explorer.
The error Invalid field: table_cell_properties originates from the erroneously specified fields property
See documentation:
fields
At least one field must be specified. The root tableCellProperties is implied and should not be specified. A single "*" can be used as short-hand for listing every field.
So you need to modify fields
from
"fields": "tableCellProperties"
to
"fields": "tableCellBackgroundFill.solidFill.color"
or to
"fields": "*"
There is a second problem with your request:
When specifying the table range, it is required to set the properties rowSpan and columnSpan.
A complete, correct request would be:
{
"requests": [
{
"updateTableCellProperties": {
"objectId": "gf9d8fea71f_22_1",
"tableRange": {
"location": {
"columnIndex": 0,
"rowIndex": 1
},
"rowSpan": 1,
"columnSpan": 1
},
"fields": "tableCellBackgroundFill.solidFill.color",
"tableCellProperties": {
"tableCellBackgroundFill": {
"solidFill": {
"color": {
"themeColor": "LIGHT1"
}
}
}
}
}
}
]
}

updateShapeProperties complaining about missing fields property

Details
OS: Manjaro Linux
Node.js version: 10
npm version: 6
googleapis version: 51.0.0
Steps to reproduce
We are sending a google slide API request with updateShapeProperties:
"updateShapeProperties": {
"objectId": objectId,
"shapeProperties": {
"shapeBackgroundFill": {
"solidFill": {
"color": {
"rgbColor": {
"red": r,
"green": g,
"blue": b
}
},
"alpha": 1
}
},
"outline": {
"outlineFill": {
"solidFill": {
"color": {
"rgbColor": {
"red": 0,
"green": 0,
"blue": 0
}
},
"alpha": 0.1
}
},
},
"contentAlignment": "MIDDLE"
},
"fields": "*"
}
where objectId comes from one of any pageElement we get from slide.pageElements
We get a 400 response that states:
message: ""Invalid requests[2].updateShapeProperties: At least one field must be listed in 'fields'. (Use '*' to indicate all fields.)
This somehow used to work the past few months, and was wondering why it suddenly doesn't work right now. Did we have any changes or updates on the updateShapeProperties API?
I believe that [2] of Invalid requests[2].updateShapeProperties is the request body in your question. When I tested your request body, I could replicate your situation. The error message is At least one field must be listed in 'fields'. (Use '*' to indicate all fields.). When I tested "fields": "", I got the same error message. From this situation, I thought that it might be a bug.
When I searched this situation at the Google issue tracker, I found it. Ref
So as the current workaround, in order to avoid this error, in your request body, how about the following modification?
From:
"fields": "*"
To:
"fields": "shapeBackgroundFill,outline,contentAlignment"

get distinct values of string field using elasticsearch query Client java API

I'm using elasticsearch 5.4
I need to get distinct values of fields using elasticsearch query
I'm trying this query but is not wokring
GET /index/index_type/_search
{
"size": 0,
"aggs": {
"distinct": {
"terms": {
"field": "status"
}
}
}
thank you
solution with client java api elasticsearch 5.4
import org.elasticsearch.search.aggregations.AggregationBuilders;
import org.elasticsearch.search.aggregations.bucket.terms.Terms;
TransportClient client;
SearchResponse response = client.prepareSearch(indexName).setTypes(typeName)
.addAggregation(AggregationBuilders.terms("distinct_line_status").field("line_status.keyword"))
.setSize(0).get();
//AggregationProfileShardResult searchHits = response.getAggregations().getAsMap();
System.out.println(response);
Terms genders = response.getAggregations().get("distinct_line_status");
// For each entry
for (Terms.Bucket entry : genders.getBuckets()) {
System.out.println(entry.getKey()); // Term
System.out.println(entry.getDocCount()); // Doc count
}
You can use cardinality to achieve this.
GET /index/index_type/_search
{
"size": 0,
"aggs": {
"distinct": {
"cardinality": {
"field": "status"
}
}
}

Elastic Search - Performing Geo Location Query on Bulk imported JSON

I have a file modified.json containing JSON documents which contain the following:
{"index":{"_index": "trial", "_type": "trial", "_id":"1"}}
{"clinics" : [{"price": 1048, "city": "Bangalore", "Location": {"lon": 77.38381692924742, "lat": 12.952155989068519}}, {"price": 1048, "city": "Bangalore", "Location": {"lon": 77.38381692924742, "lat": 12.952155989068519}}]
.... And more similar documents. I am running a bulk insert through this command:
curl -s -XPOST 'http://localhost:9200/_bulk' --data-binary #modified.json
Next, through the Sense (Google Chrome) plugin, I am issuing the following request
Server: localhost:9200/trial/trial
PUT _search
{
"mappings": {
"clinics": {
"properties": {
"Location": {"type": "geo_point"}
}
}
}
}
I don't know whether or not this is creating a mapping for the Location fields.
After issuing a search request, like this:
Server: localhost:9200/trial/trial
GET _search
{
"query": {
"filtered" : {
"query" : {
"match_all" : {}
},
"filter" : {
"geo_distance" : {
"distance" : "20km",
"Location" : {
"lat" : 12.958487287824958,
"lon" : 77.69648881178146
}
}
}
}
}
}
I am getting an error saying:
failed to find geo_point field [Location]]; }]",
Please help me regarding this. Also, if possible also guide me on how to do faceted search on this data, to show clinics within a range of distance: like between 20 and 30 kilometers
You need to reverse your ordering. PUT your mapping mapping first and then do the bulk insert.
By putting the map before the insert you are letting ES know what the datatype are so that it can index them correctly. ES allows you to add mappings to an existing index but the data that's already there isn't going to get re-indexed automatically. (This is a known issue).

How to make elasticsearch add the timestamp field to every document in all indices?

Elasticsearch experts,
I have been unable to find a simple way to just tell ElasticSearch to insert the _timestamp field for all the documents that are added in all the indices (and all document types).
I see an example for specific types:
http://www.elasticsearch.org/guide/reference/mapping/timestamp-field/
and also see an example for all indices for a specific type (using _all):
http://www.elasticsearch.org/guide/reference/api/admin-indices-put-mapping/
but I am unable to find any documentation on adding it by default for all documents that get added irrespective of the index and type.
Elasticsearch used to support automatically adding timestamps to documents being indexed, but deprecated this feature in 2.0.0
From the version 5.5 documentation:
The _timestamp and _ttl fields were deprecated and are now removed. As a replacement for _timestamp, you should populate a regular date field with the current timestamp on application side.
You can do this by providing it when creating your index.
$curl -XPOST localhost:9200/test -d '{
"settings" : {
"number_of_shards" : 1
},
"mappings" : {
"_default_":{
"_timestamp" : {
"enabled" : true,
"store" : true
}
}
}
}'
That will then automatically create a _timestamp for all stuff that you put in the index.
Then after indexing something when requesting the _timestamp field it will be returned.
Adding another way to get indexing timestamp. Hope this may help someone.
Ingest pipeline can be used to add timestamp when document is indexed. Here, is a sample example:
PUT _ingest/pipeline/indexed_at
{
"description": "Adds indexed_at timestamp to documents",
"processors": [
{
"set": {
"field": "_source.indexed_at",
"value": "{{_ingest.timestamp}}"
}
}
]
}
Earlier, elastic search was using named-pipelines because of which 'pipeline' param needs to be specified in the elastic search endpoint which is used to write/index documents. (Ref: link) This was bit troublesome as you would need to make changes in endpoints on application side.
With Elastic search version >= 6.5, you can now specify a default pipeline for an index using index.default_pipeline settings. (Refer link for details)
Here is the to set default pipeline:
PUT ms-test/_settings
{
"index.default_pipeline": "indexed_at"
}
I haven't tried out yet, as didn't upgraded to ES 6.5, but above command should work.
You can make use of default index pipelines, leverage the script processor, and thus emulate the auto_now_add functionality you may know from Django and DEFAULT GETDATE() from SQL.
The process of adding a default yyyy-MM-dd HH:mm:ss date goes like this:
1. Create the pipeline and specify which indices it'll be allowed to run on:
PUT _ingest/pipeline/auto_now_add
{
"description": "Assigns the current date if not yet present and if the index name is whitelisted",
"processors": [
{
"script": {
"source": """
// skip if not whitelisted
if (![ "myindex",
"logs-index",
"..."
].contains(ctx['_index'])) { return; }
// don't overwrite if present
if (ctx['created_at'] != null) { return; }
ctx['created_at'] = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss").format(new Date());
"""
}
}
]
}
Side note: the ingest processor's Painless script context is documented here.
2. Update the default_pipeline setting in all of your indices:
PUT _all/_settings
{
"index": {
"default_pipeline": "auto_now_add"
}
}
Side note: you can restrict the target indices using the multi-target syntax:
PUT myindex,logs-2021-*/_settings?allow_no_indices=true
{
"index": {
"default_pipeline": "auto_now_add"
}
}
3. Ingest a document to one of the configured indices:
PUT myindex/_doc/1
{
"abc": "def"
}
4. Verify that the date string has been added:
GET myindex/_search
An example for ElasticSearch 6.6.2 in Python 3:
from elasticsearch import Elasticsearch
es = Elasticsearch(hosts=["localhost"])
timestamp_pipeline_setting = {
"description": "insert timestamp field for all documents",
"processors": [
{
"set": {
"field": "ingest_timestamp",
"value": "{{_ingest.timestamp}}"
}
}
]
}
es.ingest.put_pipeline("timestamp_pipeline", timestamp_pipeline_setting)
conf = {
"settings": {
"number_of_shards": 2,
"number_of_replicas": 1,
"default_pipeline": "timestamp_pipeline"
},
"mappings": {
"articles":{
"dynamic": "false",
"_source" : {"enabled" : "true" },
"properties": {
"title": {
"type": "text",
},
"content": {
"type": "text",
},
}
}
}
}
response = es.indices.create(
index="articles_index",
body=conf,
ignore=400 # ignore 400 already exists code
)
print ('\nresponse:', response)
doc = {
'title': 'automatically adding a timestamp to documents',
'content': 'prior to version 5 of Elasticsearch, documents had a metadata field called _timestamp. When enabled, this _timestamp was automatically added to every document. It would tell you the exact time a document had been indexed.',
}
res = es.index(index="articles_index", doc_type="articles", id=100001, body=doc)
print(res)
res = es.get(index="articles_index", doc_type="articles", id=100001)
print(res)
About ES 7.x, the example should work after removing the doc_type related parameters as it's not supported any more.
first create index and properties of the index , such as field and datatype and then insert the data using the rest API.
below is the way to create index with the field properties.execute the following in kibana console
`PUT /vfq-jenkins
{
"mappings": {
"properties": {
"BUILD_NUMBER": { "type" : "double"},
"BUILD_ID" : { "type" : "double" },
"JOB_NAME" : { "type" : "text" },
"JOB_STATUS" : { "type" : "keyword" },
"time" : { "type" : "date" }
}}}`
the next step is to insert the data into that index:
curl -u elastic:changeme -X POST http://elasticsearch:9200/vfq-jenkins/_doc/?pretty
-H Content-Type: application/json -d '{
"BUILD_NUMBER":"83","BUILD_ID":"83","JOB_NAME":"OMS_LOG_ANA","JOB_STATUS":"SUCCESS" ,
"time" : "2019-09-08'T'12:39:00" }'
