Description
図1は、実施形態1に係る情報収集システム2000を例示するブロック図である。図1において、矢印は情報の流れを表している。さらに、図1において、各ブロックは、ハードウエア単位の構成ではなく、機能単位の構成を表している。
情報収集システム2000は、サーバ装置3000、複数のエッジ装置4000、及び収集ルール格納部5000を有する。サーバ装置3000は、エッジ装置4000から情報を収集する装置である。以下、それぞれの装置及び格納部について具体的に説明する。
エッジ装置4000は、第1情報生成部4020及び第2情報生成部4040を有する。第1情報生成部4020は、第1情報を生成する。第1情報生成部4020が生成する第1情報は、その第1情報生成部4020を有するエッジ装置4000又はそのエッジ装置4000が監視する機器(以下、監視対象機器)の状態に関する情報である。第2情報生成部4040は、第2情報を生成する。第2情報生成部4040が生成する第2情報は、第1情報と同じ内容を含む情報であってもよいし、第1情報以外の情報を少なくとも含む情報であってもよい。
収集ルール格納部5000は、エッジ装置4000と、サーバ装置3000がそのエッジ装置4000から取得する第1情報とに対応づけて、収集ルールを格納する。収集ルールは、第2情報に含める情報の内容、第2情報を取得する頻度、及びこの収集ルールを適用するエッジ装置4000のいずれか1つ以上を示す。
サーバ装置3000は、第1情報取得部3020、第2情報取得部3040、及び収集ルール取得部3060を有する。第1情報取得部3020は、エッジ装置4000から第1情報を取得する。第2情報取得部3040は、エッジ装置4000から第2情報を取得する。収集ルール取得部3060は、第1情報取得部3020によって取得された第1情報とその第1情報の生成元であるエッジ装置4000とに対応する収集ルールを、収集ルール格納部5000から取得する。
サーバ装置3000とエッジ装置4000とは、通信ネットワーク10を介して接続されている。通信ネットワーク10は、有線回線で構成されていてもよいし、無線回線で構成されていてもよいし、有線回線と無線回線を混在させて構成されていてもよい。
本実施形態の情報収集システム2000によれば、エッジ装置4000及びそのエッジ装置4000から取得する第1情報に基づいて、第2情報の収集に関する収集ルールが取得される。ここで、収集ルールは、第2情報に含める情報の内容、第2情報を取得する頻度、及びこの収集ルールを適用するエッジ装置4000のいずれか1つ以上を示す。したがって、エッジ装置4000及び第1情報の各組み合わせに対して、第2情報の収集によって情報収集システム2000にかかる負荷を予測しておき、情報収集システム2000にかかる負荷が小さくなるように適切な収集ルールを収集ルール格納部5000に格納しておく。こうすることで、情報収集システム2000全体にかかる負荷を総合的に考慮して、第2情報の収集を行うことができる。その結果、サーバ装置3000やエッジ装置4000の一部が高負荷で動作できなくなる等といった弊害が発生する確率を小さくすることができる。
サーバ装置3000及びエッジ装置4000が有する各機能構成部は、例えば、個々に又は複数組み合わせられた状態で、少なくとも1つのハードウエア構成要素として実現される。その他にも例えば、各機能構成部は、少なくとも1つのソフトウエア構成要素として実現される。その他にも例えば、各機能構成部は、ハードウエア構成要素とソフトウエア構成要素の組み合わせにより実現される。
サーバ装置3000は、種々の計算機である。例えばサーバ装置3000は、PC(Personal Computer)、サーバ計算機、携帯端末、又はタブレット PC などである。
エッジ装置4000は、種々の計算機である。例えばエッジ装置4000は、携帯端末又はタブレット PCなどである。ただし、エッジ装置4000は、PC やサーバ計算機などでもよい。
収集ルール格納部5000がサーバ装置3000の外部に設けられる場合、例えば収集ルール格納部5000は、ネットワークストレージやデータベースサーバとして実現される。収集ルール格納部5000がサーバ装置3000の内部に設けられている場合については、前述した通りである。
図4は、実施形態1の情報収集システム2000において実行される処理の流れを例示するフローチャートである。ステップS102において、第1情報生成部4020は、第1情報を生成する。ステップS104において、第1情報取得部3020は、第1情報を取得する。ステップS106において、収集ルール取得部3060は、第1情報取得部3020によって取得された第1情報とその第1情報の生成元であるエッジ装置4000とに対応する、収集ルールを取得する。ステップS108において、第2情報生成部4040は、第2情報を生成する。ステップS110において、第2情報取得部3040は、第2情報を取得する。
第1情報生成部4020によって生成される第1情報は様々である。例えば第1情報生成部4020は、その第1情報生成部4020を有するエッジ装置4000又はそのエッジ装置4000の監視対象機器において、異常が発生しているか否かを判定する。そして、第1情報生成部4020は、この異常判定の結果を示す第1情報を生成する。
第2情報生成部4040によって生成される第2情報は様々である。例えば、第2情報は、エッジ装置4000又はそのエッジ装置4000の監視対象機器で発生している異常に関する詳細な情報を示す。例えば、この詳細な情報は、異常の内容、エッジ装置4000若しくは監視対象機器の現在の詳細なステータス、又はエッジ装置4000若しくは監視対象機器のステータスに関するログなどである。
第1情報取得部3020が第1情報を取得する方法は様々である。例えば第1情報取得部3020は、エッジ装置4000によって送信された第1情報を受信することで、第1情報を取得する。この場合、エッジ装置4000は、サーバ装置3000へそのエッジ装置4000の第1情報を送信する、第1情報送信部4060を有する。図5は、エッジ装置4000が第1情報送信部4060を有する場合の情報収集システム2000を例示するブロック図である。
第2情報取得部3040が第2情報を取得する方法は様々である。例えば第2情報取得部3040は、エッジ装置4000によって送信される第2情報を受信することで、第2情報を取得する。図7は、エッジ装置4000によって第2情報が送信される場合における情報収集システム2000を例示するブロック図である。
前述したように、収集ルールは、第2情報に含める情報の内容、第2情報を取得する頻度、及びこの収集ルールを適用するエッジ装置4000のいずれか1つ以上を示す。例えば第1情報が、エッジ装置4000が有する特定のハードウエアに異常が発生していることを示すとする。この場合、例えば第2情報に含める内容は、その特定のハードウエアに関する詳細なステータスである。
図9は、収集ルール格納部5000に格納されている情報をテーブル形式で例示する図である。図9に示すテーブルを、収集ルールテーブル200と表記する。収集ルールテーブル200の各レコードは、レコード ID 202、シグナルセット206、内容208、頻度210、適用対象212、優先度214、及び適用回数216を示す。レコード ID 202は、レコードの ID を示す。シグナルセット206は、収集ルールに対応付ける「エッジ装置4000、第1情報」の組み合わせを表す。例えば、図9の1行目のレコードのシグナルセット206は、「エッジ E1、x = s0 という第1情報」の組み合わせを表す。つまり、第1情報取得部3020がエッジ E1 から、x = s0 という第1情報を取得した場合、収集ルール取得部3060は、図9の1行目のレコードが示す収集ルールを取得する。
図10は、実施形態2に係る情報収集システム2000を例示するブロック図である。図10において、矢印は情報の流れを表している。さらに、図10において、各ブロックは、ハードウエア単位の構成ではなく、機能単位の構成を表している。
さらに、実施形態2のサーバ装置3000は、上限値格納部3080に格納されている負荷上限値を更新する機能を有していてもよい。情報収集システム2000が許容できる負荷の上限値である負荷上限値は、変動する可能性がある。例えば、第2情報以外にも通信ネットワーク10を介してやりとりされる情報があるため、そのやりとりによって通信ネットワーク10にかかる負荷が変動する場合などが考えられる。そこで、サーバ装置3000は、情報収集システム2000の負荷に関する情報を取得し、この情報に従って、負荷上限値を更新する。
本実施形態によれば、情報収集システム2000にかかる負荷を考慮して、第2情報の収集が行われる。具体的には、適用される収集ルールの収集負荷の合計値が、負荷上限値以下になるように、適用する収集ルールを決定する。こうすることで、第2情報の収集によって情報収集システム2000が高負荷になることを防ぐことができる。

実施形態3の情報収集システム2000は、生成ルール格納部6000を有する。生成ルール格納部6000は、生成ルールを格納する。生成ルールは、第1情報及びその第1情報を生成したエッジ装置4000に対応づけられており、第1情報の生成に関するルールを示す。
サーバ装置3000は、生成ルール取得部3120及び生成ルール送信部3140を有する。生成ルール取得部3120は、第1情報取得部3020によって取得された第1情報及びその第1情報を生成したエッジ装置4000に対応する生成ルールを、生成ルール格納部6000から取得する。生成ルール送信部3140は、エッジ装置4000に対応する生成ルールを、そのエッジ装置4000へ送信する。
エッジ装置4000は、生成ルールを受信する生成ルール受信部4120を有する。また、実施形態3の第1情報生成部4020は、生成ルール受信部4120が生成ルールを受信した場合、その生成ルールを用いて第1情報を生成する。
生成ルール取得部3120は、第1情報に対応する生成ルールを取得する。そのため、エッジ装置4000は、生成ルール送信部3140から生成ルールを取得する前の時点で、第1情報を生成する必要がある。そのために、例えば各エッジ装置4000に対して、デフォルトの生成ルールを設定しておく。そして、第1情報生成部4020は、生成ルール受信部4120が生成ルール送信部3140から生成ルールを取得するまでの間、上記デフォルトの生成ルールに従って第1情報を生成する。
図15は、生成ルール格納部6000に格納されている情報をテーブル形式で例示する図である。図15に示すテーブルを、生成ルールテーブル300と表記する。サーバ装置3000の各レコードは、レコード ID 302、シグナルセット306、及び生成ルール308を示す。レコード ID 302は、レコードのIDである。シグナルセット306は、生成ルールに対応付ける「エッジ装置4000、第1情報」の組み合わせを示す。シグナルセット306は、図9のシグナルセット206と同様に、「エッジ装置4000、第1情報」の複数の組み合わせを示してもよい。
図16は、実施形態3の情報収集システム2000において実行される処理の流れを例示する図である。ステップS302において、第1情報生成部4020は、第1情報を生成する。ステップS304において、第1情報取得部3020は、第1情報を取得する。ステップS306において、生成ルール取得部3120は、ステップS304で取得した第1情報と、その第1情報の生成元であるエッジ装置4000とに対応する生成ルールを、生成ルール格納部6000から取得する。ステップS308において、生成ルール送信部3140は、エッジ装置4000に対して生成ルールを送信する。ステップS310において、エッジ装置4000は、生成ルールを受信する。ステップS312において、第1情報生成部4020は、生成ルールに基づいて第1情報を生成する。
本実施形態において、第1情報生成部4020は、生成ルールに基づいて第1情報を生成する。そのため、各エッジ装置4000による第1情報の生成ルールを、生成ルール格納部6000で一元管理することができる。したがって、第1情報の生成ルールの管理(生成ルールの変更など)が容易になる。
