Good afternoon,
I would like to know if there is any way to convert the data collected by SNMP from bit to Gb.
I'm trying to monitor a disk and it gives me the used and total space in bits.
With this operation I could do:"%(hrStorageEntry.hrStorageUsed) * 100 / %(hrStorageEntry.hrStorageSize)"
but I don't know where to do it so that it is executed and saved in a variable, so that it can be printed later. I have tried the following tutorial:
But it doesn't work for me, since the "function" is for count the result. Is there any function that can do what I am saying (multiply or divide the collected metrics inside de JSON structure)? I guess it will have to be executed within the selection_loop, because I need to calculate it for each line returns.
Could you give me the list of functions that can be used? I can't find any information either on GitHub, or on TheWatch, or in the documentation about what functions I can use with snmp mode collection or about the json structure.
My Json configuration is:
{
"snmp": {
"tables": t
{
"name": "hrStorageEntry",
"oid": "1.3.6.1.2.1.25.2.3.1",
"used_instance": "\\.(\\d+)$",
"entries": +
{"name": "hrStorageDescr", "oid": "1.3.6.1.2.1.25.2.3.1.3"},
{"name": "hrStorageSize", "oid": "1.3.6.1.2.1.25.2.3.1.5"},
{"name": "hrStorageUsed", "oid": "1.3.6.1.2.1.25.2.3.1.6"}
]
}
]
},
"selection_loop": /
{

"hrStorageEntry": "%(snmp.tables.hrStorageEntry.e%(hrStorageEntry.instance)])"
},

],

}
}
],
