Automatic export all logs and send by mail

[gdimaria]

Hi, 

I need to constantly monitor about 80 objects and I thought the best way was to automatically export logs every month and send them by email.

The questions are:

is it possible to do it and if so how?

Is there enough memory in LM to hold the 30-day logs of 80 objects or is it better to use an external USB memory? Here, too, how can I do?

Thanks for your kind response

Hi, use this example http://openrb.com/example-export-last-ho...-from-lm2/

and file in attach

cant attach file

see code below (it has russian comments)

Code:

-- temp файл


filepath = os.tmpname()
-- получаем время  начала  записи за последний час (3600 секунд)
logtime = os.time() - 60 * 60

-- Список  объектов по id

Hi,

have anyone this code working?

I tried, but it looks like the mail will not sent.

when i open the pop-up logs, i see the record of my history

and the message

Code:

log by mail 17.01.2022 05:22:05
* file (0x01f6b5a0)

what looks good for me.


i also tried to use, just for sure if mail is working
E-mail backup file once a month from LM

when i run this script i got the error

Code:

test mail bakup 17.01.2022 05:24:44
* string: 555 5.5.2 Syntax error. w19sm3726342ejb.140 - gsmtp

i use a gmail account without 2fa and i use it on another server, without problems.

maybe a wrong version of ssl?

Escaping of the "to" address was missing.
Here's a rewritten script with clearer structure. You only need to modify the to/settings/subject at the to top of the script. SSL settings do not matter anymore because newer SSL library automatically negotiates the highest supported SSL/TLS version between server/client.

Code:

to = 'to@example.com'

settings = {
  -- "from" field, only e-mail must be specified here
  from = 'sender@example.com',
  -- smtp username
  user = 'sender@example.com',
  -- smtp password
  password = '12345678',
  -- smtp server
  server = 'smtp.gmail.com',
  -- smtp server port
  port = 465,
  -- enable ssl, required for gmail smtp
  secure = 'sslv23',
}

subject = 'CSV logs'

logtime = os.time() - 60 * 60 -- last hour (3600 seconds)

buffer = {'"date","address","name","value"'}

query = [[
  SELECT o.id, o.datatype, o.name, ol.datahex, ol.logtime, ol.eventtype
  FROM objectlog ol
  JOIN objects o ON ol.address=o.id
  WHERE ol.logtime >= ?
  ORDER BY ol.id DESC
]]

for _, row in ipairs(db:getall(query, logtime)) do
  if row.datatype and row.eventtype == 'write' then
    data = grp.decodevalue(row.datahex, row.datatype)
    logdate = os.date('%Y.%m.%d %H:%M:%S', row.logtime)

    buffer[ #buffer + 1 ] = string.format('%q,%q,%q,%q',
      logdate, knxlib.decodega(row.id), row.name, tostring(data))
  end
end

csv = table.concat(buffer, '\r\n')

smtp = require('socket.smtp')
mime = require('mime')
ltn12 = require('ltn12')

function escape(v)
  return '<' .. tostring(v) .. '>'
end

to = escape(to)

msgt = {
  headers = {
    to = to,
    ['content-type'] = 'text/csv',
    ['content-disposition'] = 'attachment; filename="logs.csv"',
    ['content-transfer-encoding'] = 'BASE64',
    subject = subject,
  },
  body = ltn12.source.chain(
    ltn12.source.string(csv),
    ltn12.filter.chain(mime.encode('base64'), mime.wrap('base64'))
  )
}

settings.source = smtp.message(msgt)
settings.from = escape(settings.from)
settings.rcpt = { to }

res, err = smtp.send(settings)
log(res, err)

[Dré]

The script is working fine,
but is it also possible to send the results to two email addresses?

[admin]

Try this:

Code:

to = {
  escape('user1@example.com'),
  escape('user2@example.com'),
}

msgt = {
  headers = {
    to = table.concat(to, ', '),
    ['content-type'] = 'text/csv',
    ['content-disposition'] = 'attachment; filename="logs.csv"',
    ['content-transfer-encoding'] = 'BASE64',
    subject = subject,
  },
  body = ltn12.source.chain(
    ltn12.source.string(csv),
    ltn12.filter.chain(mime.encode('base64'), mime.wrap('base64'))
  )
}

settings.source = smtp.message(msgt)
settings.from = escape(settings.from)
settings.rcpt = to

[Dré]

Thanks is it working, except there was a little mistake:
at line 10 there is missing a ']' after '['content-disposition''

---

another question.
I also want to make a export from just 1 object, is that also possible?
group adres 4/0/22 with the name: 'Inbraak In=0 / Uit=1-geschakeld'

[admin]

If you want to send a generic alert via email then use an event script like in this example: https://forum.logicmachine.net/showthread.php?tid=3330

[Dré]

Actually, no, this is not what I'm looking for.

The customer has an alarm system, and many times there is a discussion if it was on at night or not.
So he will look at the log if the alarm system was activated, so he would look at the log to see if it is on.
At the moment he gets a mail of the last 24 hours with all the events. (only when he pressed a button for sending the mail).
I would do almost the same but just for the event of the alarm system was turned on, with a larger time period.
so mostly he dont have to know, only when there is a discussion about it.
so i would make a second button, to sent a mail with this log.

[admin]

Use this for a single group address. CSV is rather pointless in this case. This script simply shows dates and values in the message body.

Code:

id = buslib.encodega('0/0/1')
to = { 'to1@example.com', 'to2@example.com' }
subject = 'Alarm logs'

logtime = os.time() - 24 * 60 * 60 -- last 24 hours

buffer = {}

query = [[
  SELECT o.datatype, ol.datahex, ol.logtime, ol.eventtype
  FROM objectlog ol
  JOIN objects o ON ol.address=o.id
  WHERE o.id=? AND ol.logtime >= ?
  ORDER BY ol.id DESC
]]

for _, row in ipairs(db:getall(query, id, logtime)) do
  if row.datatype and row.eventtype == 'write' then
    data = grp.decodevalue(row.datahex, row.datatype)
    logdate = os.date('%Y.%m.%d %H:%M:%S', row.logtime)
    buffer[ #buffer + 1 ] = logdate .. ' ' .. tostring(data)
  end
end

message = table.concat(buffer, '\r\n')
mail(to, subject, message)

I have different users who all have his own panel to control the lights/gates.

Great thanks again, it is working

[Dré]

I have a question,
I have a client panel, sometimes it has problems and need to reboot.
The panel login automatic and it always show the visualisation page.

My question, is it possible to record when someone login and who?
I don't mean when someone executes a command, but really logging in to the server on a client pc.

And when this is possible, is it also possible to sent it by mail (on request or automatic)?

I will use this script to notify me, when something happened.
Is it possible to use this script not by a adress but with a tag?

Escaping of the "to" address was missing.
Here's a rewritten script with clearer structure. You only need to modify the to/settings/subject at the to top of the script. SSL settings do not matter anymore because newer SSL library automatically negotiates the highest supported SSL/TLS version between server/client.

Code:

to = 'to@example.com'

settings = {
  -- "from" field, only e-mail must be specified here
  from = 'sender@example.com',
  -- smtp username
  user = 'sender@example.com',
  -- smtp password
  password = '12345678',
  -- smtp server
  server = 'smtp.gmail.com',
  -- smtp server port
  port = 465,
  -- enable ssl, required for gmail smtp
  secure = 'sslv23',
}

subject = 'CSV logs'

logtime = os.time() - 60 * 60 -- last hour (3600 seconds)

buffer = {'"date","address","name","value"'}

query = [[
  SELECT o.id, o.datatype, o.name, ol.datahex, ol.logtime, ol.eventtype
  FROM objectlog ol
  JOIN objects o ON ol.address=o.id
  WHERE ol.logtime >= ?
  ORDER BY ol.id DESC
]]

for _, row in ipairs(db:getall(query, logtime)) do
  if row.datatype and row.eventtype == 'write' then
    data = grp.decodevalue(row.datahex, row.datatype)
    logdate = os.date('%Y.%m.%d %H:%M:%S', row.logtime)

    buffer[ #buffer + 1 ] = string.format('%q,%q,%q,%q',
      logdate, knxlib.decodega(row.id), row.name, tostring(data))
  end
end

csv = table.concat(buffer, '\r\n')

smtp = require('socket.smtp')
mime = require('mime')
ltn12 = require('ltn12')

function escape(v)
  return '<' .. tostring(v) .. '>'
end

to = escape(to)

msgt = {
  headers = {
    to = to,
    ['content-type'] = 'text/csv',
    ['content-disposition'] = 'attachment; filename="logs.csv"',
    ['content-transfer-encoding'] = 'BASE64',
    subject = subject,
  },
  body = ltn12.source.chain(
    ltn12.source.string(csv),
    ltn12.filter.chain(mime.encode('base64'), mime.wrap('base64'))
  )
}

settings.source = smtp.message(msgt)
settings.from = escape(settings.from)
settings.rcpt = { to }

res, err = smtp.send(settings)
log(res, err)

Hello Admin,

I would like to have something similar but instead of sending the logs by mail just export per 24h all logs to the LM ftp. Or if possible if the database of 50k points is full then export to the internal ftp.
The task I need to achieve is a long period of telegrams recording and analyzing in a later phase. the period would be something about two weeks to one month.
Is this possible or not?

Regards Manos

Constantly writing to LM SD card will kill it sooner or later. If you want to analyze large batches of data then you should export it to an external database like influxdb. See this thread for examples: https://forum.logicmachine.net/showthread.php?tid=1531
