I'm new to json and want to extract data (blocks) from a specific json. I've tried to find information on how to do this with jq but so far I cannot seem to get what I want.
My json:
{
"now" : 1589987097.9,
"aircraft" : [
{
"mlat" : [],
"rssi" : -26.2,
"track" : 319,
"speed" : 354,
"messages" : 16,
"seen" : 0.7,
"altitude" : 38000,
"vert_rate" : 0,
"hex" : "44b5b4",
"tisb" : []
},
{
"squawk" : "6220",
"altitude" : 675,
"seen" : 1.1,
"messages" : 7220,
"tisb" : [],
"hex" : "484a95",
"mlat" : [],
"rssi" : -22
},
{
"hex" : "484846",
"tisb" : [],
"messages" : 20,
"speed" : 89,
"seen" : 0.4,
"squawk" : "7000",
"altitude" : 500,
"rssi" : -23.7,
"track" : 185,
"mlat" : []
},
{
"category" : "B1",
"mlat" : [],
"rssi" : -24.3,
"flight" : "ZSGBX ",
"altitude" : 3050,
"squawk" : "7000",
"seen" : 16.8,
"messages" : 37,
"tisb" : [],
"hex" : "00901a"
}
],
"messages" : 35857757
}
I would like to reformat this json to only include 'blocks' that contain specific hex values.
So for example, I want I would like my output to contain 44b5b4 and 00901a:
{
"now" : 1589987097.9,
"aircraft" : [
{
"mlat" : [],
"rssi" : -26.2,
"track" : 319,
"speed" : 354,
"messages" : 16,
"seen" : 0.7,
"altitude" : 38000,
"vert_rate" : 0,
"hex" : "44b5b4",
"tisb" : []
},
{
"category" : "B1",
"mlat" : [],
"rssi" : -24.3,
"flight" : "ZSGBX ",
"altitude" : 3050,
"squawk" : "7000",
"seen" : 16.8,
"messages" : 37,
"tisb" : [],
"hex" : "00901a"
}
],
"messages" : 35857757
}
Can someone tell me how to remove all items not having those 2 hex identifiers but still keep the same json structure?
Thanks a lot!
Do a select() on the array aircraft, matching only the required hex values. The map() function takes input the entire array and the result of the select operation i.e. filtering of objects based on the .hex value is updated back |= to the original array and the rest of the fields are kept intact.
jq '.aircraft |= map(select(.hex == "44b5b4" or .hex == "00901a"))' json
Select blocks whose hex matches one of the specific values and update aircraft to leave only those.
.aircraft |= map(select(.hex | IN("44b5b4", "00901a")))

I'm trying to retrieve the data from this dictionary and for some reason I cannot seem to acquire it. I'm new to parsing JSON so apologies if this is rough.
let temp = json["list"].arrayValue.map({$0["main"].dictionaryValue})
print(temp[0])
Here I am setting a value equal to the dictionary from the JSON. However, I know I need to add the key's value that I'm searching for. To be clear, I am searching for the "temp" key which in the example is equal to 28.19999...
Here is an example of the JSON:
"list" : [
{
"dt" : 1641524400,
"main" : {
"humidity" : 68,
"sea_level" : 1014,

Found my answer:
let temp = json["list"].arrayValue.map({$0["main"]["temp"].stringValue})

What you posted doesn't look like a valid JSON to me.
If in reality you're getting what's in your image, to wit:
{
"data": "{ \"took\" : 13, \"timed_out\" : false, \"_shards\" : { \"total\" : 5, \"successful\" : 5, \"skipped\" : 0, \"failed\" : 0 }, \"hits\" : { \"total\" : 1, \"max_score\" : 1.0, \"hits\" : [ { \"_index\" : \"bushidodb_history_network_eval_ea9656ef-0a9b-474b-8026-2f83e2eb9df1_2021-april-10\", \"_type\" : \"network\", \"_id\" : \"6e2e58be-0ccf-3fb4-8239-1d4f2af322e21618059082000\", \"_score\" : 1.0, \"_source\" : { \"misMatches\" : [ \"protocol\", \"state\", \"command\" ], \"instance\" : \"e3032804-4b6d-3735-ac22-c827950395b4|0.0.0.0|10.179.155.155|53|UDP\", \"protocol\" : \"UDP\", \"localAddress\" : \"0.0.0.0\", \"localPort\" : \"12345\", \"foreignAddress\" : \"10.179.155.155\", \"foreignPort\" : \"53\", \"command\" : \"pingyahoo.com\", \"user\" : \"testuser1\", \"pid\" : \"10060\", \"state\" : \"OUTGOINGFQ\", \"rate\" : 216.0, \"originalLocalAddress\" : \"192.168.100.229\", \"exe\" : \"/bin/ping\", \"md5\" : \"f9ad63ce8592af407a7be43b7d5de075\", \"dir\" : \"\", \"agentId\" : \"abcd-dcd123\", \"year\" : \"2021\", \"month\" : \"APRIL\", \"day\" : \"10\", \"hour\" : \"12\", \"time\" : \"1618059082000\", \"isMerged\" : false, \"timestamp\" : \"Apr10, 202112: 51: 22PM\", \"metricKey\" : \"6e2e58be-0ccf-3fb4-8239-1d4f2af322e2\", \"isCompliant\" : false }, \"sort\" : [ 1618059082000 ] } ] }, \"aggregations\" : { \"count_over_time\" : { \"buckets\" : [ { \"key_as_string\" : \"2021-04-10T08: 00: 00.000-0400\", \"key\" : 1618056000000, \"doc_count\" : 1 } ] } }}",

the easiest way is just using 2 JSON Extractors:
Extract data attribute value into a JMeter Variable from the response
Extract user attribute value into a JMeter variable from ${data} JMeter Variable:
Demo:
If the response looks like exactly you posted you won't be able to use JSON Extractors and will have to treat it as normal text so your choice is limited to Regular Expression Extractor, example regular expression:
"user"\s*:\s*"(\w+)"
Add Regular Expression extractor with the corresponding request and extract it. Use the below expression.
Expression: "user" : "(.*?)"

Regular Expression Extractor Sample
I found the solution for json to csv conversion. Below is the sample json and solution.
{
"took" : 111,
"timed_out" : false,
"_shards" : {
"total" : 1,
"successful" : 1,
"skipped" : 0,
"failed" : 0
},
"hits" : {
"total" : {
"value" : 2,
"relation" : "eq"
},
"max_score" : 1.0,
"hits" : [
{
"_index" : "alerts",
"_type" : "_doc",
"_id" : "1",
"_score" : 1.0,
"_source" : {
"alertID" : "639387c3-0fbe-4c2b-9387-c30fbe7c2bc6",
"alertCategory" : "Server Alert",
"description" : "Successfully started.",
"logId" : null
}
},
{
"_index" : "alerts",
"_type" : "_doc",
"_id" : "2",
"_score" : 1.0,
"_source" : {
"alertID" : "2",
"alertCategory" : "Server Alert",
"description" : "Successfully stoped.",
"logId" : null
}
}
]
}
}
The solution :
jq -r '.hits.hits[]._source | [ "alertID" , "alertCategory" , "description", "logId" ], ([."alertID",."alertCategory",."description",."logId" // "null"]) | #csv' < /root/events.json
The problem with this solution is that I have to hard code the column names. What If my json gets a few additions under _source tag later? I need a solution which can handle the dynamic data under _source. I am open to any other tool or command in shell.
Simply use keys_unsorted (or keys if you want them sorted). See e.g. Convert JSON array into CSV using jq or How to convert arbitrary simple JSON to CSV using jq? for two SO examples. There are many others too.
I have 2 Json values that are similar, but there are some differences.
Json1:
{
"id": "1",
"people" : [
{
"Id" : 1421,
"Name" : "Jackson",
"Age" : 21,
"Status" : "Available"
},
{
"Id" : 5916,
"Name" : "Steven",
"Age" : 22,
"Status" : "Available"
}
],
"totalRecords" : 2
}
Json2:
{
"id": "1",
"people" : [
{
"Id" : 1421,
"Name" : "Jackson",
"Age" : 21,
"Status" : "Available"
},
{
"Id" : 5916,
"Name" : "Steven",
"Age" : 22,
"Status" : "Unavailable"
},
{
"Id" : 1337,
"Name" : "Alice",
"Age" : 19,
"Status" : "Available"
}
],
"totalRecords" : 3
}
I'd like to know if there's a way to compare the two Jsonvalues. At the moment I de-serialize the data into a type and then use the Id's and the status' to see if anythings changed. I then pick out the parts that are different (In the example it'd be Steven and Alice) and add them to a sequence for later.
I'd like to reverse a few of the steps. I'd like too compare the json, find the differences, deserialize them and then add them to the sequence, or add them to the sequence then de-serialize the whole sequence. Either way, same result.
Any ideas?
Problem with mongoDB
I have a collection in my mongodb with the following colums:
{"_id" : ObjectId("5443cddc425e215c7290a179"), "orderid" : 1002854, "customerid" : 45978, "campaignid" : 2141, "orderdate" : "2009-10-13 00:00:00", "city" : "NEWTON", "state" : "MA", "zipcode" : 2459, "paymenttype" : "VI", "totalprice" : 190, "numorderlines" : 3, "numunits" : 3}
There are 239 different campaignid's, which all should have a value of 1, but they all have 0.
Now i want to have per campaignid the total amount of numunits grouped, which i use the following statement:
db.orders.aggregate({$group: {_id: "$campaignid", Numunits: {$sum:" $numunits"}}})
It gives back the following result:
{ "_id" : 2146, "Numunits" : 0} , { "_id" : 2111, "Numunits" : 0} etc...
Now the expected result is:
{ "_id": 2146, "Numunits" : 93} , { "_id" : 2111, "Numunits" : 23} etc..
Mongo doesn't trim space for you if any. Try this:
db.orders.aggregate(
[
{$group: {
_id: "$campaignid",
Numunits: {$sum:"$numunits"}
}
}
])
