Check if you have started all the mongod instances that you want to include as a replica with --replSet. I resolved this issue by restarting the instances with said option.

I trying using Jmeter to extract out the value of agentID, how can I do that using Jmeter, what would be better ? using extractor or json extractor?
what I am trying to do is to extract agentID value in order to use it on another http request sample, but first I have to extract it from this request.
thanks!
I believe using JSON Extractor is the best way to get this agentID value, the relevant JsonPath query will be as simple as $..agentID
Demo:
See the following reference material:
JsonPath - Getting Started - for initial information regarding JsonPath language, functions, operators, etc.
JMeter's JSON Path Extractor Plugin - Advanced Usage Scenarios - for more complex scenarios.
I am trying to do some basic validation on my firebase database to ensure when an order is submitted that both email and mobile are present.
This is the rule I thought who achieve this but I am getting an error in the simulator say write access denied
{
"rules": {
"Orders": {
".read": true,
".write": true,
"$order_id": {
".validate": "newData.hasChildren(['email', 'phone'])"
}
}
}
}
This is the child node of /Orders
"-KeDyBIqnzNik0vOCEfQ" : {
"date" : "2017-03-02T23:22:32+1100",
"email" : "beanindustries#gmail.bean",
"items" : [ {
"description" : "Almond",
"name" : "Cappuccino",
"price" : ".5",
"qty" : 1
}, {
"description" : "Almond",
"name" : "Cappuccino",
"price" : ".5",
"qty" : 1
} ],
"name" : "Mr Bean",
"notes" : "\n\n",
"phone" : "0412258499",
"status" : "new"
}
So, it turns out I wasnt using data section within the simulator which is why my validations failed. I have since pasted the above JSON into that box and the validations appear to be working as expected
I currently have a Mongo DB database with one collection ('locations') with one document:
{
"_id" : ObjectId("5875653b89513c8328416522"),
"name" : "Starcups",
"address" : "125 High Street, Reading, RG6 1PS",
"rating" : 3,
"facilities" : [
"Hot drinks",
"Food",
"Premium wifi"
],
"coords" : [
-0.9690884,
51.455041
],
"openingTimes" : [
{
"days" : "Monday - Friday",
"opening" : "7:00am",
"closing" : "7:00pm",
"closed" : false
},
{
"days" : "Saturday",
"opening" : "8:00am",
"closing" : "5:00pm",
"closed" : false
},
{
"days" : "Sunday",
"closed" : true
}
],
"reviews" : [
{
"author" : "Simon Holmes",
"id" : ObjectId("5875663389513c8328416523"),
"rating" : 5,
"timestamp" : ISODate("2013-07-15T23:00:00Z"),
"reviewText" : "What a great place. I can't say enough good things about it."
}
]
}
I need to alter the field "id" (part of the subdocument reviews) to "_id". I have tried, using other similar examples on StackExchange, the following code to no avail:
db.locations.update({}, {$rename:{"reviews.id":"reviews._id"}}, false, true);
But I receive the following error:
WriteResult({
"nMatched" : 0,
"nUpserted" : 0,
"nModified" : 0,
"writeError" : {
"code" : 16837,
"errmsg" : "cannot use the part (reviews of reviews.id) to traverse the element ({reviews: [ { author: \"Simon Holmes\", id: ObjectId('5875663389513c8328416523'), rating: 5.0, timestamp: new Date(1373929200000), reviewText: \"What a great place. I can't say enough good things about it.\" } ]})"
}
})
I get the same error when I try to alter any other field. Could someone point me in the right direction?
Update:
This seems to be a problem assessing the subdocument field as the following code executes fine:
db.locations.update({}, {$rename:{"name":"names"}}, false, true);
I have also tried searching through the relevant documentation: https://docs.mongodb.com/manual/reference/operator/update/rename/
That's because Reviews is an Array
You cannot $rename to do that , instead you need to $set the new name and $unset the old one
I want update a array value that is nested within an array value: i.e. set
status = enabled
where alerts.id = 2
{
"_id" : ObjectId("5496a8ed49847b6cd7c7b350"),
"name" : "joe",
"locations" : [
{
"name": "my location",
"alerts" : [
{
"id" : 1,
"status" : null
},
{
"id" : 2,
"status" : null
}
]
}
]
}
I would have used the position $ character, but cannot use it twice in a statement - multi positional operators are not supported yet: https://jira.mongodb.org/browse/SERVER-831
How do I issue a statement to only update the status field of an alert matching an id of 2?
UPDATE
If I change the schema as follows:
{
"_id" : ObjectId("5496ab2149847b6cd7c7b352"),
"name" : "joe",
"locations" : {
"my location" : {
"alerts" : [
{
"id" : 1,
"status" : "enabled"
},
{
"id" : 2,
"status" : "enabled"
}
]
},
"my other location" : {
"alerts" : [
{
"id" : 3,
"status" : null
},
{
"id" : 4,
"status" : null
}
]
}
}
}
I can then use:
update({"locations.my location.alerts.id":1},{$set: {"locations.my location.alerts.$.status": "enabled"}});
Problem is I cannot create indexes on the alert id :-(
it may be better of modelled as such, specially if an index on location and,or alerts.id is needed.
{
"_id" : ObjectId("5496a8ed49847b6cd7c7b350"),
"name" : "joe",
"location" : "myLocation",
"alerts" : [{
"id" : 1,
"status" : null
},
{
"id" : 2,
"status" : null
}
]
}
{
"_id" : ObjectId("5496a8ed49847b6cd7c7b350"),
"name" : "joe",
"location" : "otherLocation",
"alerts" : [{
"id" : 1,
"status" : null
},
{
"id" : 2,
"status" : null
}
]
}
I think you are having a wrong tool for the job. What you have in your example is relational data and it's much easier to handle with relational database. So I would suggest to use SQL-database instead of mongo.
But if you really want to do it with mongo, then I guess the only option is to fetch the document and modify it and put it back.
I have a Spring Roo project I am trying to create based on log4mongo-java appender and I want to get access to the data entries that looks like:
{
"_id" : ObjectId("4f16cd30b138685057c8ebcb"),
"timestamp" : ISODate("2012-01-18T13:46:24.704Z"),
"level" : "INFO", "thread" : "catalina-exec-8180-3",
"message" : "method execution[execution(TerminationComponent.terminateCall(..))]",
"loggerName" :
{ "fullyQualifiedClassName" : "component_logger",
"package" : ["component_logger"],
"className" : "component_logger"
},
"properties" : {
"cookieId" : "EDE44DC03EB65D91657885A34C80595E"
},
"fileName" : "LoggingAspect.java",
"method" : "logForComponent",
"lineNumber" : "81", "class" : {
"fullyQualifiedClassName" : "com.comcast.ivr.core.aspects.LoggingAspect",
"package" : ["com", "comcast", "ivr", "core", "aspects", "LoggingAspect"],
"className" : "LoggingAspect"
},
"host" : {
"process" : "2220#pacdcivrqaapp01",
"name" : "pacdcivrqaapp01",
"ip" : "24.40.31.85"
},
"applicationName" : "D2",
"eventType" : "Development"
}
The timestamp looks like:
"timestamp" : ISODate("2012-01-17T22:30:19.839Z")
How can I add a field in my Logging domain object to map this field?
That's just the JavaScript Date (according to the mongo docs, and as can be demonstrated in the shell), so try with java.util.Date.
