According the Universal Verification Methodology (UVM) e User Guide of Cadence:
The events recognized by the monitor depend on the actual protocol. Typically, for the basic data item the monitor
provides an item_started and an item_ended event (for example, packet_started and packet_ended). The monitor collects
the item data from the signals and creates a current_item that has the complete item data, ready to be used when the
item_ended event occurs. In addition to the raw data, the monitor should collect relevant timing information such as the
duration of the transaction.
I try to execute the following in my agent by:
connect_ports() is also {
uart_monitor.uart_frame_s_started.connect(tx_scb.uart_frame_s_add);
uart_monitor.uart_frame_s_ended.connect(tx_scb.uart_frame_s_match);
};
I get the following errors: Error: 'uart_monitor' (of 'uart_tx_monitor_u') does not have 'uart_frame_S_started'field.... Error: 'uart_monitor' (of 'uart_tx_monitor_u') does not have 'uart_frame_S_ended'field
But when I declare the events in the monitor by:
event uart_frame_s_started;
event uart_frame_s_ended;
There are no errors.
Why should I declare those events if they are supposed to be provided by the monitor?
are you using the uvm scoreboard? if so, its ports (add and match) are TLM ports. meaning - they expect to get data item written to them.
but you connect to them event ports.
there is something strange - in your code, the events names have a lower 's', but in the error - as you print it - there is capital S. is it uart_frame_s_started or uart_frame_S_started ?

I want to search the last message for a few strings and then echo the message back with those strings replaced with other strings.
I searched multiple documentations but didn't find a way to get the last message.
This is the first forum I ask as I already have an account so have no real starting point to give you.
Thanks in advance!
There is no way in the WoW API to get the last chat message of a specific channel. You will have to handle the CHAT_MSG_CHANNEL event (see Event Handling) to read all messages, and store the newest one. Specifically for the say or yell (shout) channels there are the CHAT_MSG_SAY and CHAT_MSG_YELL events respectively.
To do this your addon needs to own a Frame, these frames can register event handlers and you will have to store the last message you receive from that handler in a local variable in your script (let's call it last_message). Then when your other piece of code executes you can read the last_message variable:
local frame = CreateFrame("FRAME", "FooAddonFrame");
local last_message = nil;
frame:RegisterEvent("CHAT_MSG_CHANNEL");
local function eventHandler(self, event, ...)
-- Look up the arguments that are given to your specific event
-- and assign them to variables in order by retrieving them from
-- the `...` variable arguments
local msg, author, language, channel = ...
print("Hello World! Hello " .. event);
last_message = msg
end
frame:SetScript("OnEvent", eventHandler);
I have an application deployed on PCF and have a new relic service binded to it. In new relic I want to get an alert when my application is stopped . I don't know whether it is possible or not. If it is possible can someone tell me how?
Edit: I don't have access to New Relic Infrastructure
Although an 'app not reporting' alert condition is not built into New Relic Alerts, it's possible to rig one using NRQL alerts. Here are the steps:
Go to New Relic Alerts and begin creating a NRQL alert condition:
NRQL alert conditions
Query your app with:
SELECT count(*) FROM Transaction WHERE appName = 'foo'
Set your threshold to :
Static
sum of query results is below x
at least once in y minutes
The query runs once per minute. If the app stops reporting then count will turn the null values into 0 and then we sum them. When the number goes below whatever your threshold is then you get a notification. I recommend using the preview graph to determine how low you want your transactions to get before receiving a notification. Here's some good information:
Relic Solution: NRQL alerting with “sum of the query results”
Basically you need to create a NewRelic Alert with conditions that check if application available, Specially you can use Host not reporting alert condition
The Host not reporting event triggers when data from the Infrastructure agent does not reach the New Relic collector within the time frame you specify.
You could do something like this:
// ...
aggregation_method = "cadence" // Use cadence for process monitoring otherwise it might not alert
// ...
nrql {
// Limitation: only works for processes with ONE instance; otherwise use just uniqueCount() and set a LoS (loss of signal)
query = "SELECT filter(uniqueCount(hostname), WHERE processDisplayName LIKE 'cdpmgr') OR -1 FROM ProcessSample WHERE GENERIC_CONDITIONS FACET hostname, entityGuid as 'entity.guid'"
}
critical {
operator = "below"
threshold = 0
threshold_duration = 5*60
threshold_occurrences = "ALL"
}
Previous solution - turned out it is not that robust:
// ...
critical {
operator = "below"
threshold = 0.0001
threshold_duration = 600
threshold_occurrences = "ALL"
}
nrql {
query = "SELECT percentage(uniqueCount(entityAndPid), WHERE commandLine LIKE 'yourExecutable.exe') FROM ProcessSample FACET hostname"
}
This will calculate the fraction your process has against all other processes.
If the process is not running the percentage will turn to 0. If you have a system running a vast amount of processes it could fall below 0.0001 but this is very unprobable.
The advantage here is that you can still have an active alert even if the process slips out of your current time alert window after it stopped. Like this you prevent the alert from auto-recovering (compared to just filtering with WHERE).
I have an iPhone app, where I want to show how many people are currently viewing an item as such:
I'm doing that by running this transaction when people enter a view (Rubymotion code below, but functions exactly like the Firebase iOS SDK):
listing_reference[:listings][self.id][:viewing_amount].transaction do |data|
data.value = data.value.to_i + 1
FTransactionResult.successWithValue(data)
end
And when they exit the view:
listing_reference[:listings][self.id][:viewing_amount].transaction do |data|
data.value = data.value.to_i + -
FTransactionResult.successWithValue(data)
end
It works fine most of the time, but sometimes things go wrong. The app crashes, people loose connectivity or similar things.
I've been looking at "onDisconnect" to solve this - https://firebase.google.com/docs/reference/ios/firebasedatabase/interface_f_i_r_database_reference#method-detail - but from what I can see, there's no "inDisconnectRunTransaction".
How can I make sure that the viewing amount on the listing gets decremented no matter what?
A Firebase Database transaction runs as a compare-and-set operation: given the current value of a node, your code specifies the new value. This requires at least one round-trip between the client and server, which means that it is inherently unsuitable for onDisconnect() operations.
The onDisconnect() handler is instead a simple set() operation: you specify when you attach the handler, what write operation you want to happen when the servers detects that the client has disconnected (either cleanly or as in your problem case involuntarily).
The solution is (as is often the case with NoSQL databases) to use a data model that deals with the situation gracefully. In your case it seems most natural to not store the count of viewers, but instead the uid of each viewer:
itemViewers
$itemId
uid_1: true
uid_2: true
uid_3: true
Now you can get the number of viewers with a simple value listener:
ref.child('itemViewers').child(itemId).on('value', function(snapshot) {
console.log(snapshot.numChildren());
});
And use the following onDisconnect() to clean up:
ref.child('itemViewers').child(itemId).child(authData.uid).remove();
Both code snippets are in JavaScript syntax, because I only noticed you're using Swift after typing them.
Here i created a router with SmallestMailboxRouter
ActorRef actorRouter = this?.getContext()?.actorOf(new Props(RuleStandardActor.class).withRouter(new SmallestMailboxRouter(38)),"standardActorRouter")
Now in for loop i created 38 actors
for(int i=0;i <38;i++) {
ruleStandardActorRouter?.tell(new StandardActorMessage(standard: standard, responseVO: responseVO, report: report), getSelf());
}
each actor will process the logic and returns the score and message . i am receiving the message by overriding onreceive method and adding them to a list
If i run the program multiple times i am getting different scores. but it should return always same score as i am giving same input.
if (message instanceof StandardActorResponse) {
StandardActorResponse standardActorResponse = message
standardActorResponseList?.add(standardActorResponse)
}
here standardActorResponse contains message and score . if i am using same logic by just using for loop instead of akka framework i am reciving conisstant result. but in akka randomly getting different results. for example i have some rules like loginexistence and navigationexistence and alertsexistence rules. i have given one html source to these rules to check whether the html source have login,alerts,navigation links in that source. some times i am getting login doesnt exists, some times navigation doesnt exist, some times alerts doesnt exists by using akka routers and actors. but if i use for loop i am always getting same result
can any one help me to find the problem. i am using akka 2.1.4
Probably the for loop is already finished before the mailbox size is recognised. Try adding a sleep in the for loop to see the results.
I'm writing a program where the user must enter a 'yes' or 'no' value. The following is the code that will be executed when the message {createPatient,PatientName} is received.
{createPatient, PatientName} ->
Pid = spawn(patient,newPatient,[PatientName]),
register(PatientName,Pid),
io:format("*--- New Patient with name - ~w~n", [PatientName]),
Result = io:read("Yes/No> "),
{_,Input} = Result,
if(Input==yes) ->
io:format("OK")
end,
loop(PatientRecords, DoctorPatientLinks, DoctorsOnline, CurrentPatientRequests, WaitingOfflineDoctorRequests);
When executed ,the line "New Patient with name..." is displayed however the line Yes/No is not displayed and the program sort of crashes because if another message is sent, then the execution of that message will not occur. Is there a different way to solve this problem please?
There are a number of points I would like to make here:
The io:read/1 function reads a term, not just a line, so you have to terminate input with a '.' (like in the shell).
io:read/1 returns {ok,Term} or {error,Reason} or eof so you code should check for these values, for example with a case.
As #AlexeyRomanov mentioned, io:get_line/1 might be a better choice for input.
The if expression must handle all cases even the ones in which you don't want to do anything, otherwise you will get an error. This can be combined with the case testing the read value.
You spawn the function patient:newPatient/1 before you ask if the name is a new patient, this seems a little strange. What does the newpatient function do? Is it in anyway also doing io to the user which might be interfering with functions here?
The main problem seems to be work out what is being done where, and when.
This is very artificial problem. In erlang any communication is usually inter-process and exchanging strings wouldn't make any sense - you ask question in context of process A and you would like to post answer in context of process B (shell probably).
Anyways, consider asking question and waiting in receive block in order to get an answer.
When question pops out in shell, call a function which will send the answer to 'asking' process with your answer.
So:
io:format("*--- New Patient with name - ~w~n", [PatientName]),
receive
{answer, yes} -> do_something();
{answer, no} -> do_something()
end
The 'answering' function would look like that:
answer(PatientName, Answer) ->
PatientName ! {answer, Answer}.
And shell action:
$> *--- New Patient with name - User1036032
$> somemodule:answer('User1036032', yes).
It is possible to create some dialog with shell (even unix shell), but to be honest it is used so rare that I do not remember those I/O tricks with read and write. http://trapexit.com/ used to have cookbook with this stuff.
Use io:get_line("Yes/No> ") instead.
