QUESTION
When the below code errors (ping()
rejects its promise), I get the warning. The HTTP function seems to error out just fine. Something must be happening in ping()
itself, I guess, which is somehow avoiding the try-catch.
Could someone enlighten me? (This is after a few attempts at changing things to get it working.)

is the javascript construct which converts the rejection of the promise to an exception.
That is, await
is the construct which handles the rejection.

QUESTION
I have created an MVP for a nodejs project, following are some of the features that are relevant to the question I am about to ask:
1-The application has a list of IP addresses with CRUD actions. 2-The application will ping each IP address after every 5 seconds. 3- And display against each IP address it's status i.e alive or dead and the uptime if alive
I created a working MVP on nodejs with the help of the library net-ping, express, mongo and angular. Now I have a new feature request that is:
"to calculate the round trip time(latency) for each ping that is generated for each IP address and populate a bar chart or any type of chart that will display the RTT(latency) history(1 months-1 year) of every connection"
I need to store the response of each ping in the database, Assuming the best case that if each document that I will store is of size 0.5 kb, that will make 9.5MB data to be stored in each day,285MB in each month and 3.4GB in a year for a single IP address and I am going to have 100-200 IP addresses in my application.
What is the best solution (including those which are paid) that will suit the best for my requirements considering the app can scale more?
...ANSWER
Answered 2018-May-24 at 00:40Time series data require special treatment from a database perspective as they introduce challenges to the traditional database management from capacity, query performance, read/write optimisation targets, etc.
I wouldn't recommend you store this data in a traditional RDBMS, or object/document database.
Best option is to use a specialised time-series database engine, like InfluxDB, that can support downsampling (aggregation) and raw data retention rules
